2011-22812. Energy Conservation Program: Test Procedures for Residential Dishwashers, Dehumidifiers, and Conventional Cooking Products (Standby Mode and Off Mode)

AGENCY:

Office of Energy Efficiency and Renewable Energy, Department of Energy.

ACTION:

Supplemental notice of proposed rulemaking.

SUMMARY:

Where appropriate, the U.S. Department of Energy (DOE) has proposed to amend its test procedures for residential dishwashers, dehumidifiers, and conventional cooking products (which includes cooktops, ovens, and ranges) to include provisions for measuring standby mode and off mode energy consumption, as required by the Energy Independence and Security Act of 2007 (EISA 2007). These test procedure amendments would incorporate by reference certain provisions of the International Electrotechnical Commission (IEC) Standard 62301, “Household electrical appliances—Measurement of standby power.” Since publication of DOE's initial proposal in December 2010, the IEC has replaced the First Edition of this standard with the current Second Edition. This supplemental notice of proposed rulemaking proposes to incorporate the latest edition of IEC Standard 62301.

I. Authority and Background

Title III, Part B ^[1] of the Energy Policy and Conservation Act of 1975 (EPCA or the Act), Public Law 94-163 (42 U.S.C. 6291-6309, as codified) sets forth a variety of provisions designed to improve energy efficiency and established the Energy Conservation Program for Consumer Products Other Than Automobiles, a program covering most major household appliances.^[2] These include residential dishwashers, conventional cooking products,^[3] and dehumidifiers, the subject of today's notice. (42 U.S.C. 6292(a)(6) and (10); 6295(cc))

Under the Act, this program consists essentially of four parts: (1) Testing, (2) labeling, (3) establishing Federal energy conservation standards, and (4) certification and enforcement procedures. The testing requirements consist of test procedures that manufacturers of covered products must use: (1) As the basis for certifying to DOE that their products comply with applicable energy conservation standards adopted pursuant to EPCA, and (2) for making representations about the efficiency of those products. (42 U.S.C. 6293(c); 6295(s)) Similarly, DOE must use these test procedures in any enforcement action to determine whether the products comply with these energy conservation standards. (42 U.S.C. 6295(s))

A. General Test Procedure Rulemaking Process

Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. EPCA provides in relevant part that “[a]ny test procedures prescribed or amended under this section shall be reasonably designed to produce test results which measure energy efficiency, energy use * * * or estimated annual operating cost of a covered product during a representative average use cycle or period of use, as determined by the Secretary [of Energy], and shall not be unduly burdensome to conduct.” (42 U.S.C. 6293(b)(3))

In addition, if DOE determines that a test procedure amendment is warranted, it must publish proposed test procedures and offer the public an opportunity to present oral and written comments on them. (42 U.S.C. 6293(b)(2)) Finally, in any rulemaking to amend a test procedure, DOE must determine “to what extent, if any, the proposed test procedure would alter the measured energy efficiency * * * of any covered product as determined under the existing test procedure.” (42 U.S.C. 6293(e)(1)) If DOE determines that the amended test procedure would alter the measured efficiency of a covered product, DOE must amend the applicable energy conservation standard accordingly. (42 U.S.C. 6293(e)(2))

On December 19, 2007, the Energy Independence and Security Act of 2007 (EISA 2007), Public Law 110-140, was enacted. The EISA 2007 amendments to EPCA, in relevant part, require DOE to amend the test procedures for all residential covered products to include measures of standby mode and off mode energy consumption. Specifically, section 310 of EISA 2007 provides definitions of “standby mode” and “off mode” (42 U.S.C. 6295(gg)(1)(A)) and permits DOE to amend these definitions in the context of a given product (42 U.S.C. 6295(gg)(1)(B)). The statute requires integration of such energy consumption “into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product, unless the Secretary determines that—

(i) The current test procedures for a covered product already fully account for and incorporate the standby mode and off mode energy consumption of the covered product; or

(ii) Such an integrated test procedure is technically infeasible for a particular covered product, in which case the Secretary shall prescribe a separate standby mode and off mode energy use test procedure for the covered product, if technically feasible.” (42 U.S.C. 6295(gg)(2)(A))

Under the statutory provisions adopted by EISA 2007, any such amendment must consider the most current versions of IEC Standard 62301, “Household electrical appliances—Measurement of standby power,” and IEC Standard 62087, “Methods of measurement for the power consumption of audio, video, and related equipment.” ^[4] Id. At the time of the enactment of EISA 2007, the most current versions of these standards were IEC Standard 62301 (First Edition 2005-06) and IEC Standard 62087 (Second Edition 2008-09).

1. Dishwashers

DOE's test procedure for dishwashers is found in the Code of Federal Regulations (CFR) at 10 CFR part 430, subpart B, appendix C. DOE originally established its test procedure for dishwashers in 1977. 42 FR 39964 (August 8, 1977). Since that time, the dishwasher test procedure has undergone a number of amendments, as discussed below. In 1983, DOE amended the test procedure to revise the representative average-use cycles to more accurately reflect consumer use and to address dishwashers that use 120 °F inlet water. 48 FR 9202 (March 3, 1983). DOE amended the test procedure again in 1984 to redefine the term “water heating dishwasher.” 49 FR 46533 (Nov. 27, 1984). In 1987, DOE amended the test procedure to address models that use 50 °F inlet water. 52 FR 47549 (Dec. 15, 1987). In 2001, DOE revised the test procedure's testing specifications to improve testing repeatability, changed the definitions of “compact dishwasher” and “standard dishwasher,” and reduced the average number of use cycles per year from 322 to 264. 66 FR 65091, 65095-97 (Dec. 18, 2001). In 2003, DOE again revised the test procedure to more accurately measure dishwasher efficiency, energy use, and water use. The 2003 dishwasher test procedure amendments included the following revisions: (1) the addition of a method to rate the efficiency of soil-sensing products; (2) the addition of a method to measure standby power; and (3) A reduction in the average-use cycles per year from 264 to 215. 68 FR 51887, 51899-903 (August 29, 2003). The current version of the test procedure includes provisions for determining estimated annual energy use (EAEU), estimated annual operating cost (EAOC), energy factor (EF) expressed in cycles per kilowatt-hour (kWh), and water consumption expressed in gallons per cycle. 10 CFR 430.23(c).

2. Dehumidifiers

The DOE test procedure for dehumidifiers is found at 10 CFR 430, subpart B, appendix X. The Energy Policy Act of 2005 (EPACT 2005), Public Law 109-58, amended EPCA to specify that the U.S. Environmental Protection Agency's (EPA) test criteria used under the ENERGY STAR® ^[5] program must serve as the basis for the test procedure for dehumidifiers. (EPACT 2005, section 135(b); 42 U.S.C. 6293(b)(13)) The ENERGY STAR test criteria require that American National Standards Institute (ANSI)/Association of Home Appliance Manufacturers (AHAM) Standard DH-1-2003, “Dehumidifiers,” be used to measure energy use and that the Canadian Standards Association (CAN/CSA) standard CAN/CSA-C749-1994 (R2005), “Performance of Dehumidifiers,” be used to calculate EF. DOE has adopted these test criteria, along with related definitions and tolerances, as its test procedure for dehumidifiers. 71 FR 71340, 71347, 71366-68 (Dec. 8, 2006). The DOE test procedure provides methods for determining the EF for dehumidifiers, which is expressed in liters (l) of water condensed per kWh.

3. Conventional Cooking Products

DOE's test procedures for conventional ranges, cooktops, and ovens (including microwave ovens) are found at 10 CFR 430, subpart B, appendix I. DOE first established the test procedures included in appendix I in a final rule published in the Federal Register on May 10, 1978. 43 FR 20108, 20120-28. DOE revised its test procedure for cooking products to more accurately measure their efficiency and energy use, and published the revisions as a final rule in 1997. 62 FR 51976 (Oct. 3, 1997). These test procedure amendments included: (1) a reduction in the annual useful cooking energy; (2) a reduction in the number of self-cleaning oven cycles per year; and (3) incorporation of portions of IEC Standard 705-1988, “Methods for measuring the performance of microwave ovens for household and similar purposes,” and Amendment 2-1993 for the testing of microwave ovens. Id. The test procedure for conventional cooking products establishes provisions for determining EAOC, cooking efficiency (defined as the ratio of cooking energy output to cooking energy input), and EF (defined as the ratio of annual useful cooking energy output to total annual energy input). 10 CFR 430.23(i); 10 CFR 430 subpart B, appendix I. These provisions for conventional cooking products are not currently used for compliance with any energy conservation standards (because those standards currently involve design requirements), nor is there an EnergyGuide ^[6] labeling program for cooking products.

DOE has initiated a separate test procedure rulemaking to address standby mode and off mode power consumption for microwave ovens. This rulemaking was initiated separately in response to comments from interested parties on the advance notice of proposed rulemaking (ANOPR) for an earlier rulemaking concerning energy conservation standards for residential dishwashers, dehumidifiers, cooking products, and commercial clothes washers published on November 15, 2007 (hereafter referred to as the November 2007 ANOPR) (72 FR 64432), prior to the enactment of EISA 2007. As discussed in the subsequent notice of proposed rulemaking (NOPR) for that standards rulemaking, interested parties stated generally that DOE should amend the test procedures for all types of cooking products to allow for measurement of standby mode energy use in order to implement a standby power energy conservation standard. 73 FR 62034, 62043-44 (Oct. 17, 2008). However, DOE did not receive any specific data or inputs on standby power consumption in conventional cooking products. Also, at that time, interested parties did not submit any comments regarding DOE addressing new measures of standby mode and off mode energy use in the test procedures or energy conservation standards for the other products that were the subject of the November 2007 ANOPR (i.e., dishwashers and dehumidifiers). Because DOE agreed with the comments supporting new measures of standby mode and off mode energy use for microwave ovens and the potential for early adoption of an energy conservation standard for microwave ovens addressing standby mode and off mode energy consumption, DOE published a NOPR proposing amendments to just the microwave oven test procedure for standby mode and off mode in the Federal Register on October 17, 2008. 73 FR 62134. DOE subsequently published a supplemental notice of proposed rulemaking (SNOPR) in the Federal Register on this topic on July 22, 2010 (75 FR 42612), and an interim final rule on March 9, 2011 (hereafter referred to as the March 2011 Interim Final Rule) (76 FR 12825). DOE issued this as an interim final rule in order to allow comment on a newly issued version of IEC Standard 62301 (which is discussed in more detail in the following section) for measuring standby mode and off mode energy use, the previous version of which was incorporated by reference in the microwave oven test procedure. Consequently, DOE is proposing amendments to its cooking products test procedure for only conventional cooking products in today's SNOPR.

B. Standby Mode and Off Mode

Section 310 of EISA 2007 amended EPCA to require DOE to amend the test procedures for covered products to address standby mode and off mode energy consumption. Specifically, the amendments require DOE to integrate standby mode and off mode energy consumption into the overall energy efficiency, energy consumption, or other energy descriptor for that product unless the current test procedures already fully account for such consumption. If integration is technically infeasible, DOE must prescribe a separate standby mode and off mode energy use test procedure, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)) Any such amendment must consider the most current versions of IEC Standard 62301, “Household electrical appliances—Measurement of standby power,” and IEC Standard 62087, “Methods of measurement for the power consumption of audio, video, and related equipment.” Id.

C. The December 2010 NOPR

On December 2, 2010, DOE published a NOPR (hereafter called the December 2010 NOPR) in which it proposed to incorporate by reference into the test procedures for dishwashers, dehumidifiers, and conventional cooking products specific provisions from IEC Standard 62301 “Household electrical appliances—Measurement of standby power,” First Edition 2005-06 (IEC Standard 62301 (First Edition) or “First Edition”) regarding test conditions and test procedures for measuring standby mode and off mode power consumption. 75 FR 75290, 75295-97. DOE also proposed to incorporate into each test procedure the definitions of “active mode,” “standby mode,” and “off mode” that were based on the definitions for those terms provided in the most current draft at that time of an updated version of IEC Standard 62301. Id. at 75297-300. Further, DOE proposed to include in each test procedure additional language that would clarify the application of clauses from IEC Standard 62301 (First Edition) for measuring standby mode and off mode power consumption.⁷ Id. at 75300-04. DOE held a public meeting on December 17, 2010, to receive comments on the December 2010 NOPR, and accepted written comments, data, and information until February 15, 2011. Commenters to the December 2010 NOPR suggested that the draft updated version of IEC Standard 62301 would provide practical improvement to the mode definitions and testing methodology for the test procedures that are the subject of this rulemaking.

II. Summary of the Supplemental Notice of Proposed Rulemaking

Based upon the public comment received on the December 2010 NOPR, DOE decided to further analyze the draft materials associated with IEC Standard 62301 (Second Edition), which were in an advanced stage of development. Shortly thereafter, the IEC adopted and published IEC Standard 62301, “Household electrical appliances—Measurement of standby power,” Edition 2.0 2011-01 (IEC Standard 62301 (Second Edition) or “Second Edition”) on January 27, 2011. Consistent with its statutory mandate, DOE has reviewed this latest version of the IEC standard and agrees that it does provide for improvement for some measurements of standby mode and off mode energy use. Accordingly, DOE proposes in today's SNOPR to incorporate certain provisions of the IEC Standard 62301 (Second Edition), along with clarifying language, into the DOE test procedures for residential dishwashers, dehumidifiers, and conventional cooking products. Other than the specific amendments newly proposed in today's SNOPR, DOE continues to propose the test procedure amendments originally included in the December 2010 NOPR. For the reader's convenience, DOE has reproduced in this SNOPR the entire body of proposed regulatory text from the December 2010 NOPR for the residential dishwasher, dehumidifier, and conventional cooking products test procedures, further amended as appropriate according to today's proposals. DOE's supporting analysis and discussion for the portions of the proposed regulatory text not affected by this SNOPR may be found in the December 2010 NOPR. 75 FR 75290 (Dec. 2, 2010).

III. Discussion

A. Incorporation of IEC Standard 62301 (Second Edition)

As noted above, EPCA, as amended by EISA 2007, requires that test procedures be amended to include standby mode and off mode energy consumption, taking into consideration the most current versions of IEC Standards 62301 and 62087. (42 U.S.C. 6295(gg)(2)(A)) The December 2010 NOPR proposed to incorporate in the test procedures for dishwashers, dehumidifiers, and conventional cooking products relevant provisions from IEC Standard 62301 (First Edition) for measuring standby mode and off mode power. The amended test procedures would use these measured wattages in calculations to accomplish the incorporation of standby mode and off mode energy consumption into the test procedures. DOE reviewed the IEC Standard 62301 (First Edition) and tentatively concluded that it would be generally applicable to dishwashers, dehumidifiers, and conventional cooking products, although some clarification would be needed. Specifically, DOE proposed in the December 2010 NOPR for standby mode and off mode power measurements to provide a stabilization period of at least 30 minutes followed by an energy use measurement period of not less than 10 minutes for each of the covered products. 75 FR 75290, 75300 (Dec. 2, 2010). Additionally, for conventional cooking products, DOE proposed a specific standby mode power measurement methodology for units in which power varies as a function of displayed time. 75 FR 75290, 75302-04 (Dec. 2, 2010). With these clarifications in place, the December 2010 NOPR proposed to reference IEC Standard 62301 (First Edition) for the standby mode and off mode wattage measurements. (DOE notes that IEC Standard 62301 (First Edition) has been incorporated by reference in 10 CFR 430.3, “Materials incorporated by reference,” as part of recent final amendments to the furnace and boiler test procedure. 75 FR 64621 (Oct. 20, 2010).)

DOE noted in the December 2010 NOPR that there were expected to be significant differences between the first and second editions of IEC Standard 62301, based upon DOE's review of the Final Draft International Standard (FDIS) version available at that time. 75 FR 75290, 75296 (Dec. 2, 2010). For example, IEC Standard 62301 (FDIS) modified certain provisions, such as clarifying the definition of “standby mode” and “off mode” to allow for the measurement of multiple standby power modes.

As part of the December 2010 NOPR, DOE reviewed IEC Standard 62301 (FDIS) and anticipated that, once finalized, it would ultimately define the various modes differently than IEC Standard 62301 (First Edition). 75 FR 75290, 75296-97 (Dec. 2, 2010). IEC Standard 62301 (FDIS) incorporated responses to comments from multiple national committees from member countries on several previous draft versions, and thus, DOE believed, it provided the best available mode definitions. Although the revised IEC Standard 62301 (Second Edition) had not yet been officially released, DOE decided to consider the substance of the new operational mode definitions from the draft version IEC Standard 62301 (FDIS) for the December 2010 NOPR. Id. DOE noted that the mode definitions in IEC Standard 62301 (FDIS) were substantively similar to those in the previous draft version (IEC Standard 62301 Committee Draft for Vote (CDV)), which were the subject of extensive comments from interested parties during recent DOE test procedure rulemakings addressing standby mode and off mode energy use in other products (i.e., microwave ovens, clothes dryers, and room air conditioners). In those instances, interested parties indicated general support for adopting the mode definitions provided in IEC Standard 62301 (CDV). Due to the effective equivalence of the mode definitions in IEC Standard 62301 (CDV) and IEC Standard 62301 (FDIS), DOE stated in the December 2010 NOPR that the public comment support expressed for the mode definitions in IEC Standard 62301 (CDV) would extend to those in IEC Standard 62301 (FDIS). 75 FR 75290, 75297 (Dec. 2, 2010).

After considering both versions of IEC Standard 62301 (i.e., First Edition and FDIS), DOE tentatively concluded in the December 2010 NOPR that the definitions of “standby mode,” “off mode,” and “active mode” provided in IEC Standard 62301 (FDIS) were the most useful, in that they expanded upon the EPCA mode definitions and provided additional guidance as to which functions would be associated with each mode. Therefore, DOE proposed definitions of “standby mode,” “off mode,” and “active mode” based on the definitions provided in IEC Standard 62301 (FDIS) in the December 2010 NOPR. Id.

DOE noted in the December 2010 NOPR that other significant changes in the methodology of IEC Standard 62301 were first introduced only at the FDIS stage. DOE noted that those changes had not been, at that time, the subject of significant public comment from interested parties, nor had DOE had the opportunity to conduct a thorough analysis of those provisions. 75 FR 75290, 75297 (Dec. 2, 2010). Consequently, the merits of those latest changes had not been fully vetted, as would demonstrate that they would be preferable to the methodological provisions in IEC Standard 62301 (First Edition). Thus, DOE stated it was not able to determine whether the updated methodology represented the best available means to measure standby mode and off mode energy use. DOE, therefore, tentatively decided to base the proposed test procedure amendments (other than mode definitions) on the provisions of IEC Standard 62301 (First Edition). Id. (DOE notes that while the statute requires consideration of the latest version of IEC 62301, it does not require the agency to ignore other draft versions that have achieved an advanced level of vetting, such as IEC Standard 62301 (FDIS), which had already been out for a final vote among members.)

In response to the December 2010 NOPR, DOE received comments from interested parties regarding the appropriate version of IEC Standard 62301 to use in its test procedures to measure standby mode and off mode energy use. Comments made at the public meeting were predicated upon IEC Standard 62301 (FDIS) being the most current, albeit draft, version of the updated standard. By the time the NOPR comment period ended on February 15, 2011, IEC Standard 62301 (Second Edition) had published, and thus, interested parties were able to consider this version as the most current in their written submissions to DOE.

Pacific Gas and Electric Company (PG&E), Southern California Gas Company, San Diego Gas and Electric, and Southern California Edison (jointly “the California Utilities”) supported harmonizing with the mode definitions in IEC Standard 62301 (FDIS). (California Utilities, No. 16 at p. 3; PG&E, No. 17 at p. 3) ^[8] The Association of Home Appliance Manufacturers (AHAM), Northwest Energy Efficiency Alliance (NEEA), and Whirlpool Corporation (Whirlpool) supported basing the methodology as well as mode definitions on the FDIS or Second Edition of IEC Standard 62301. (AHAM, Public Meeting Transcript, No. 10 at pp. 27-30, 36 ^[9] ; NEEA, No. 11 at pp. 1-2, 5-6; Whirlpool, No. 12 at pp. 1-2) AHAM and Whirlpool supported the use of IEC Standard 62301 (Second Edition) for reasons of: (1) international harmonization; (2) clarity and consistency in testing; and (3) reduced manufacturer test burden. (Whirlpool, No. 12 at pp. 1-2, AHAM, No. 14 at p. 3)

AHAM noted that IEC Standard 62301 (FDIS), and subsequently IEC Standard 62301 (Second Edition), contain a number of important clarifications that were not present in IEC Standard 62301 (First Edition) or IEC Standard 62301 (CDV) and that would provide more accurate testing and measurement. Specifically, AHAM identified new or expanded sections on the measurement of power uncertainty, crest factor, power measurement frequency response, sampling methods, average reading methods for non-cyclic loads, and instrument measurement methods. AHAM opined that these provisions become critical in light of DOE's announced intent to require third-party testing and verification testing of very small amounts of energy in standby mode. AHAM also commented that it would be difficult to pick and choose specific sections to adopt, because IEC Standard 62301 is intended to be read as a whole and that picking certain sections out may cause problems in how they are interpreted. For example, AHAM argued that picking out a definition from IEC Standard 62301 (FDIS) and then combining that with incorporation by reference to IEC Standard 62301 (First Edition) would be inconsistent. (AHAM, No. 14 at p. 3; AHAM, Public Meeting Transcript, No. 10 at pp. 27-30)

NEEA stated that DOE has the regulatory flexibility to adjust mode definitions and test methods if it believes that a definition or procedure other than that in IEC Standard 62301 would be more appropriate. On this point, NEEA argued that IEC Standard 62301 (First Edition) is inadequate for comprehensively capturing the energy use of the broad array of products and modes that DOE is trying to cover. NEEA commented that IEC Standard 62301 (FDIS) is particularly suitable for operational modes that have cyclic or unstable power consumption. NEEA commented that any measurement period that is 5 minutes or less, as allowed in IEC Standard 62301 (First Edition), is likely to be insufficient for capturing the energy use for these modes. However, NEEA also stated there could be certain specific modes for which the less complicated procedures from IEC Standard 62301 (First Edition) might be more suitable, specifically, if DOE includes cycle-finished mode as part of active mode rather than inactive (standby) mode.^[10] (NEEA, No. 11 at pp. 1-2, 5-6)

Because IEC Standard 62301 (Second Edition) was issued on January 27, 2011, it became the most current version under the EPCA requirements at the time DOE considered comments on the December 2010 NOPR. Accordingly, DOE then conducted a comparative review of the FDIS and Second Edition versions of IEC Standard 62301, and the results of this review demonstrated that the provisions of the Second Edition are identical in substance to those of the FDIS version. Therefore, DOE interprets comments on IEC Standard 62301 (FDIS) to be equally applicable to IEC Standard 62301 (Second Edition).

DOE agrees with the commenters that IEC Standard 62301 (Second Edition) is an internationally-accepted test procedure for measuring standby power in residential appliances, and that this version provides clarification to certain sections as compared to the First Edition. Specifically, section 4, paragraph 4.4 of the Second Edition revises the power measurement accuracy provisions that were present in the First Edition. A more comprehensive specification of required accuracy is provided in the Second Edition, which depends upon the characteristics of the power being measured. Testers using the Second Edition are required to measure the crest factor and power factor of the input power, and to calculate a maximum current ratio (MCR). The Second Edition then specifies calculations to determine permitted uncertainty in MCR. DOE notes, however, that the allowable uncertainty is the same or less stringent than the allowable uncertainty specified in the First Edition, depending on the value of MCR and the power level being measured (see Table 0.1 for examples), so that sufficient accuracy of measurements is achieved under a full range of possible measured power levels without placing undue demands on the instrumentation. In addition, the wattage variations associated with the allowable uncertainty in power measurements are so small in relation to overall energy use that they would not result in measurable changes in the overall efficiency metric for dishwashers, dehumidifiers, or conventional cooking products. These power measurement accuracy requirements were based upon detailed technical submissions to the IEC in the development of IEC Standard 62301 (FDIS), which showed that commonly-used power measurement instruments were unable to meet the original requirements for certain types of loads. Therefore, DOE believes that the incremental testing burden associated with the additional measurements and calculations is offset by the more reasonable requirements for testing equipment, while maintaining measurement accuracy deemed acceptable and practical by voting members for IEC Standard 62301 (Second Edition). For these reasons, DOE proposes in today's supplemental notice to incorporate by reference the power equipment specifications in section 4, paragraph 4.4 of IEC Standard 62301 (Second Edition).

Table III.1—Comparison of Allowable Uncertainty in Measured Power

Measured power (W)	Allowable uncertainty (W)
	IEC 62301 (First edition)	IEC 62301 (Second edition)
		MCR = 5	MCR = 15
5.0	0.1	0.1	0.14
2.0	0.04	0.04	0.056
1.0	0.02	0.02	0.028
0.5	0.01	0.02	0.02
0.2	0.01	0.02	0.02

Additionally, IEC Standard 62301 (Second Edition) adds certain clarifications to the installation and setup procedures in section 5, paragraph 5.2 of the First Edition regarding products equipped with battery recharging circuits, as well as instructions for testing each relevant configuration option identified in the product's instructions for use. DOE is not aware of any dishwashers, dehumidifiers, or conventional cooking products with a recharging circuit. DOE also believes that a requirement to separately test each configuration option could substantially increase test burden and potentially conflicts with the requirement within the same section to set up the product in accordance with the instructions for use or, if no such instructions are available, to use the factory or “default” settings. Therefore, DOE tentatively concludes that the portions of the installation instructions in section 5, paragraph 5.2 of IEC Standard 62301 (Second Edition) pertaining to batteries and the requirement for the determination, classification, and testing of all modes associated with every combination of available product configuration options (which may be more numerous than the modes associated with operation at the default settings) are not appropriate for the dishwasher, dehumidifier, and conventional cooking products test procedures. Accordingly, DOE is proposing qualifying language in the test procedure amendments for these products to disregard those portions of the installation instructions.

The other major changes in the Second Edition that relate to the measurement of standby mode and off mode power consumption in covered products involve the measurement techniques and specification of the stability criteria required to measure that power. The Second Edition contains more detailed techniques to evaluate the stability of the power consumption and to measure the power consumption for loads with different stability characteristics. According to the Second Edition, the user is given a choice of measurement procedures, including sampling methods, average reading methods, and a direct meter reading method. DOE evaluated these new methods in terms of test burden and improvement in results as compared to those methods proposed in the December 2010 NOPR, which were based on IEC Standard 62301 (First Edition).

In the December 2010 NOPR, DOE proposed for all covered products to require measurement of standby mode and off mode power using section 5, paragraph 5.3 of IEC Standard 62301 (First Edition), clarified by requiring the product to stabilize for at least 30 minutes and using an energy use measurement period of not less than 10 minutes. Further, for any dishwasher or dehumidifier in which the power varies over a cycle, as described in section 5, paragraph 5.3.2 of the First Edition, the December 2010 NOPR proposed to require the use of the average power approach in section 5, paragraph 5.3.2(a), with the same 30-minute minimum stabilization and 10-minute minimum measurement periods, as long as the measurement period comprises one or more complete cycles. 75 FR 75290, 75300-01 (Dec. 2, 2010). DOE additionally proposed specific methodology for conventional cooking products in which power varies as a function of the time displayed. In that case, testers are allowed to choose measuring standby power by means of either:

(a) 10-Minute Test

(1) Allow the product to stabilize according to section 5, paragraph 5.3 of IEC Standard 62301 (First Edition), which requires a minimum of 5 minutes;

(2) Set the clock time to 3:23;

(3) Allow another stabilization period until the clock time reaches 3:33;

(4) Use the average power approach in section 5, paragraph 5.3.2(a) to measure standby mode power for a period of 10 minutes +0/−2 seconds; or

(b) 12-Hour Test

(1) At any clock time, allow the product to stabilize according to section 5, paragraph 5.3 of IEC Standard 62301 (First Edition), which requires a minimum of 5 minutes;

(2) Use the average power approach in section 5, paragraph 5.3.2(a) to measure standby mode power for a period of 12 hours +0/−30 seconds.

According to the proposal, manufacturers could elect to conduct either a 10-minute test or a 12-hour test, or both, and results of the 10-minute test that are within ± 2 percent of the results for the 12-hour test would be deemed to be representative of average energy use. Id. at 75302-04, 75328.

For today's supplemental notice, to determine the potential impacts of referencing methodology from IEC Standard 62301 (Second Edition) rather than from the First Edition, DOE compared the provisions allowed by each under different scenarios of power consumption stability.

1. Stable Power Consumption

According to section 5, paragraph 5.3.1 of IEC Standard 62301 (First Edition), power consumption is defined as stable if it varies by less than 5 percent over 5 minutes. In such a case, a direct reading may be made at the end of the measurement period. With the proposed clarifications in the December 2010 NOPR, the total test time would be at minimum 40 minutes (comprised of a minimum 30-minute stabilization period, followed by a minimum 10-minute period during which the stability criterion could be evaluated and a direct power reading taken.) Alternatively, the tester may select an average power or accumulated energy approach, again with a minimum 30-minute stabilization period and a minimum 10-minute measurement period. The average power approach would simply require a different reading to be taken from the instrument (true average power instead of a direct reading of instantaneous power), while the accumulated energy approach would require the calculation of power by dividing an accumulated energy by the duration of the measurement period.

In comparison, section 5, paragraph 5.3.4 of IEC Standard 62301 (Second Edition) specifies a direct meter reading method that can be used for stable power consumption, in which a minimum 30-minute stabilization period must be observed, followed by a first power measurement. After an additional period of 10 minutes, a second power measurement is taken. If the average of the two measurements divided by the time interval between them meets certain threshold criteria, then the power consumption is considered to be the average of the two power measurements. Thus, the total test period would still be at minimum 40 minutes. DOE agrees that this method likely improves the validity of the test results, as it is a more stringent measure of the stability of the power consumption over a longer period of time than the First Edition requires. However, if the threshold criteria are not met at the end of the test, a different measurement method must be used, increasing test time and complexity. Further, the Second Edition specifies that the direct reading method shall not be used for verification purposes. Both of these qualifications potentially increase test burden as compared to the First Edition, possibly requiring the tester to conduct the more complex methodology of the methods available under the Second Edition.

DOE notes that section 5, paragraph 5.3.2 of IEC Standard 62301 (Second Edition) identifies a sampling method as the preferred means for all power consumption measurements and the fastest test method when the power is stable. For any non-cyclic power consumption, power readings are initially recorded over a period of at least 15 minutes after energizing the product. Data from the first third of the measurement period are discarded, and stability is evaluated by a linear regression through all power readings in the second two-thirds of the data. If the slope of the linear regression is less than 10 milliwatts per hour (mW/h) for input power less than or equal to 1.0 W, or less than 1 percent of the input power per hour for input power greater than 1.0 W, the power consumption is calculated as the average of the power readings during the second two-thirds of the measurement period. If the slope of the linear regression does not meet these stability criteria, the total period is continuously extended until the stability criteria are met for the second two-thirds of the data. In some cases, this is a more stringent requirement than the stability criteria of IEC Standard 62301 (First Edition). The lack of a definitive test period means that the test duration could extend past 15 minutes for certain products—up to 3 hours is allowed in the Second Edition—and could introduce added test burden as compared to the First Edition.

2. Unstable, Non-Cyclic Power Consumption

Section 5, paragraph 5.3 from IEC Standard 62301 (First Edition), which DOE proposed in the December 2010 NOPR to incorporate by reference with clarification, specifies that either an average power method or accumulated energy approach could be used for measuring non-cyclic unstable power consumption. As described previously, the clarifications proposed in the December 2010 NOPR would limit total test duration to 40 minutes.

In contrast, the Second Edition requires the use of either a sampling method or average reading method for measuring power consumption in standby mode or off mode. The sampling method is the same as described previously, but the measurement period must be at least 60 minutes, and the cumulative average of all data points recorded during the second two-thirds of the total period must fall within a band of ± 0.2 percent.

The average reading method in section 5, paragraph 5.3.3 IEC Standard 62301 (Second Edition) comprises both an average power method and accumulated energy method, either of which may be selected for unstable, non-cyclic power. For both types of the average reading method, a 30-minute stabilization period is specified, followed by two comparison measurement periods of not less than 10 minutes each. The average power values, either measured directly or calculated from accumulated energy during each period, are compared to determine whether they agree to within certain threshold criteria. If the threshold is not achieved, the comparison periods are each extended in approximately equal increments until the threshold is met. If agreement is not achieved after reaching 30 minutes for each comparison period, the sampling method must then be used. Therefore, the minimum test period is 50 minutes, but may extend up to 90 minutes, at which time an additional test may be required.

DOE believes that the stability criteria in either method improves the accuracy and representativeness of the measurement as compared to the First Edition, but would cause the required test time to increase (potentially quite significantly), with a corresponding increase in manufacturer burden due to the additional time and complexity of the test conduct.

3. Cyclic Power Consumption

Dishwashers and Dehumidifiers

As noted previously, DOE proposed in the December 2010 NOPR for these products to use the average power approach of section 5, paragraph 5.3.2(a) in IEC Standard 62301 (First Edition), with a minimum 30-minute stabilization period and 10-minute measurement period. The First Edition also requires that at least one or more complete cycles be measured.

In the Second Edition, cyclic power must be measured according to the sampling method in section 5, paragraph 5.3.2, but this method requires a measurement period of at least four complete cycles (for a total of at least 40 minutes) divided into two comparison periods, with stability criteria evaluated by calculating the difference in average power measured in each comparison period divided by the time difference of the mid-point of each comparison period. This “slope” must be less than 10 mW/h for input powers less than or equal to 1 W, and less than 1 percent of the input power per hour for input powers greater than 1 W. If the appropriate stability criterion is not met, additional cycles are added to each comparison period until the criterion is achieved. Once stability has been reached, the power consumption is calculated as the average of all readings from both comparison periods. DOE believes that this methodology produces an improved measurement over the methodology from the First Edition, but the test duration could extend significantly longer, again potentially introducing issues of increased test burden.

Conventional Cooking Products

For conventional cooking products in which standby mode power consumption varies as a function of displayed time, DOE proposed in the December 2010 NOPR to require the use of either the 10-minute or 12-hour test methodology described previously, based on the average power approach of section 5, paragraph 5.3.2(a) of IEC Standard 62301 (First Edition). If the results of the 10-minute test agree to within ±2 percent with the results of the 12-hour test, the 10-minute test results would be deemed representative and would require a minimum of 25 minutes to conduct. If a full 12-hour test is used, total test duration would be 12 hours and 5 minutes.

Under the Second Edition, testers would be required to use the sampling method of section 5, paragraph 5.3.2 for conventional cooking products that consume varying power as a function of the displayed time due to the cyclic nature of this power consumption. Because all of the clock displays which DOE observed to be incorporated in conventional cooking products are based on a 12-hour cycle, such a product which consumes varying power as a function of the displayed time would be required under the Second Edition to be tested for a minimum of 4 cycles, or 48 hours, in addition to an initial stabilization period of not less than 10 minutes. DOE notes that this test duration would impose a greatly increased test burden on manufacturers, particularly in comparison to the previously proposed 10-minute methodology.

4. Conclusions on Test Methodology

DOE, in evaluating IEC Standard 62301 (Second Edition) in comparison to the First Edition, confers substantial weight to the considerable body of comments on and input to the provisions and methodology that IEC developed as part of its latest revision process. DOE recognizes that, in some cases, test burden and complexity would be increased by requiring the use of the test methods specified in the Second Edition. However, DOE believes that in most cases, this added burden on manufacturers has been sufficiently considered by the IEC voting members as being outweighed by the improved accuracy and representativeness of the resulting power consumption measurement. Furthermore, manufacturers were aware of these differences, but nevertheless, they overwhelmingly expressed support for DOE's use of the Second Edition. In particular, DOE tentatively concludes that the application of the provisions of the Second Edition to all power measurements in standby mode and off mode for dishwashers and dehumidifiers would be appropriate, and is proposing incorporation by reference of the relevant paragraphs of section 5.3 of IEC Standard 62301 (Second Edition) in the test procedures for these products. Further, DOE observes that although the Second Edition allows the choice of multiple test methods for both stable and unstable non-cyclic power consumption, the IEC preferred sampling method provides for a test duration that is approximately the same or shorter than the allowable IEC alternative methods and does not require classification of the nature of the power consumption (e.g., stable or unstable, non-cyclic) in advance of the test. By monitoring the variation in power consumption during the test, the test operator could determine whether it is stable or unstable, and, thus, the required duration of the sampling periods. For cyclic power consumption, the Second Edition requires the use of the sampling method. Thus, DOE proposes in today's SNOPR to specify the use of the sampling method in section 5.3.2 of IEC Standard 62301 (Second Edition) for all measures of standby mode and off mode power consumption for residential dishwashers and dehumidifiers.

Similarly, for conventional cooking products, DOE has tentatively concluded that section 5.3 of the Second Edition includes provisions that are appropriate for measuring off mode and standby modes (except in the case of a unit's clock whose power consumption varies by the time displayed), and that the sampling method in section 5.3.2 of the Second Edition would also provide for measurements with minimal test burden. Thus, DOE proposes for conventional cooking products to require the use of the sampling method in section 5.3.2 of the Second Edition, except as follows. In the narrow case of cooking products with power consumption that varies as a function of the time displayed, DOE tentatively concludes that the application of the test methodology from the Second Edition would cause manufacturers to incur significant burden that would not be warranted by any potential improved accuracy of the test measurement. For this reason, DOE continues to propose in this supplemental notice the 10-minute and 12-hour test methods for these products in the conventional cooking products test procedure. Because DOE proposes to base the other provisions incorporated by reference from IEC Standard 62301 on the Second Edition, DOE has revised its proposal regarding the 10-minute and 12-hour tests to include language equivalent to the average power method from the First Edition, without incorporating the First Edition by reference.

To this end, this supplemental notice is also proposing to amend the reference in 10 CFR 430.3 to add a reference to IEC Standard 62301 (Second Edition). DOE is not proposing to replace the reference to the First Edition in 10 CFR 430.3, because several test procedures for other covered products not addressed in today's supplemental notice incorporate provisions from it. In addition, there are a number of editorial changes necessary in the various appendices addressed in today's supplemental notice to allow for the correct referencing to the Second Edition. For example, the definition sections need to define the IEC Standard 62301 as the Second Edition instead of the First Edition. Also, there are some section numbering differences in the Second Edition which impact the text of the measurement provisions of the relevant test procedures.

DOE further notes that the proposed amendments to the cooking products test procedure would retain the references to certain provisions of IEC Standard 62301 (First Edition) which were adopted in the March 2011 Interim Final Rule for the purposes of measuring standby mode and off mode energy use in microwave ovens. As discussed above, the March 2011 Interim Final Rule invited comments on the merits of adopting additional provisions of IEC Standard 62301 (Second Edition) in the microwave oven test procedure (76 FR 12825, 12833 (March 9, 2011)), but at this time, DOE has not revised its microwave oven test procedure accordingly. Because today's supplemental notice addresses such energy use for conventional cooking products but not microwave ovens, DOE is not proposing to remove or amend the references to the First Edition in the cooking products test procedure, which contains both types of products, other than to clarify that the First Edition is being referenced for microwave ovens rather than the Second Edition. DOE's proposal for conventional cooking products, based on relevant sections of IEC Standard 62301 (Second Edition) would neither be affected by, nor impact, the testing procedures for microwave ovens other than section renumbering as appropriate.

B. Technical Corrections

Due to a transcription error in publication, the December 2010 NOPR erroneously specified certain dates in the regulatory text for the proposed test procedure amendments. Specifically, the December 2010 NOPR indicated that representations as to energy use in standby mode and off mode for dishwashers, conventional cooking products, and dehumidifiers made after May 31, 2011, would have to be based upon the proposed amended dishwasher test procedure in 10 CFR part 430, subpart B, appendix C, the amended conventional cooking products test procedure in appendix I, and the amended dehumidifier test procedure in appendix X. 75 FR 75290, 75324, 75326, 75333 (Dec. 2, 2010). Similarly, the compliance date was erroneously specified in the December 2010 NOPR as May 31, 2011, in the calculations of dishwasher estimated annual operating cost and estimated annual energy use that incorporate measures of standby mode and off mode energy use, as proposed for the test procedures in 10 CFR 430.23(c). 75 FR 75290, 75321-22 (Dec. 2, 2010). In each of these instances, the December 2010 NOPR should have specified the date as “180 days after date of publication of the test procedure final rule in the Federal Register.” DOE is proposing to make this correction to the dates in today's SNOPR, and clarifies that manufacturers would not be subject to a May 31, 2011, deadline for any of the products as part of this rulemaking.

C. Compliance With Other EPCA Requirements

1. Test Burden

EPCA requires that “[a]ny test procedures prescribed or amended under this section shall be reasonably designed to produce test results which measure energy efficiency, energy use * * * or estimated annual operating cost of a covered product during a representative average use cycle or period of use * * * and shall not be unduly burdensome to conduct.” (42 U.S.C. 6293(b)(3))

In the December 2010 NOPR, DOE noted that the proposed amendments to the residential dishwasher, dehumidifier, and conventional cooking products test procedures would incorporate a test standard that is accepted internationally for measuring power consumption in standby mode and off mode (IEC Standard 62301). DOE analyzed the available versions of IEC Standard 62301 at that time—IEC Standard 62301 (First Edition), IEC Standard 62301 (CDV), and IEC Standard 62301 (FDIS)—and determined that the proposed amendments to the residential dishwashers, dehumidifiers, and conventional cooking products test procedures would produce standby mode and off mode average power consumption measurements that are representative of an average use cycle. DOE also determined that the test methods and equipment that the amendments would require for measuring standby mode and off mode power in these products would not be substantially different from the test methods and equipment required in the current DOE tests. Thus, DOE tentatively concluded that the proposed test procedure amendments would not require manufacturers to make significant investments in test facilities and new equipment. In sum, DOE tentatively concluded in the December 2010 NOPR that the amended test procedures would produce test results that measure the standby mode and off mode power consumption during representative use, and that the test procedures would not be unduly burdensome to conduct. 75 FR 75290, 75316 (Dec. 2, 2010).

Today's supplemental proposed amendments to the DOE test procedures are based on an updated version of IEC Standard 62301, IEC Standard 62301 (Second Edition), which has been the subject of significant review and input from interested parties and, thus, continues to be an internationally accepted test standard for measuring standby mode and off mode power consumption. As discussed in section 0 of this notice, DOE believes that the provisions of IEC Standard 62301 (Second Edition) that it proposes to incorporate by reference through today's SNOPR provide a means to measure power consumption with greater accuracy and repeatability than the provisions from IEC Standard 62301 (First Edition) that were originally proposed in the December 2010 NOPR. For this reason, DOE tentatively concludes that today's supplemental proposed amendments would also provide measurements representative of average consumer use of the product under test, even if the test conditions and procedures may not be identical to average consumer use (for example, specified display times). DOE further believes these new provisions in the applicable sections of IEC Standard 62301 (Second Edition) improve test results without undue testing burden. DOE acknowledges that certain methods from IEC Standard 62301 (Second Edition) may increase test duration somewhat, but where such an increase was deemed excessive (i.e., for products with clocks that can vary in power consumption as a function of time displayed), DOE retained the method previously proposed in order to mitigate test burden. DOE also believes that the potential for increased test burden in other power consumption measurements is offset by more reasonable requirements for testing equipment, while maintaining measurement accuracy deemed acceptable and practical by voting members for IEC Standard 62301 (Second Edition). Thus, DOE tentatively concludes that the amended test procedures newly proposed in today's SNOPR would produce test results that measure the standby mode and off mode power consumption during representative use, and that the test procedures would not be unduly burdensome to conduct.

2. Potential Incorporation of IEC Standard 62087

Under 42 U.S.C. 6295(gg)(2)(A), EPCA directs DOE to consider IEC Standard 62087 when amending test procedures to include standby mode and off mode power measurements. For the December 2010 NOPR, DOE reviewed IEC Standard 62087, “Methods of measurement for the power consumption of audio, video, and related equipment” (Second Edition 2008-09), and tentatively determined that it would not be applicable to measuring power consumption of electrical appliances such as dishwashers, dehumidifiers, and conventional cooking products. Therefore, DOE tentatively concluded that referencing IEC Standard 62087 is not necessary for the proposed amendments to the test procedures that are the subject of this rulemaking. 75 FR 75290, 75316 (Dec. 2, 2010). For the same reason, DOE maintains the same tentative conclusion for today's SNOPR.

3. Integration of Standby Mode and Off Mode Energy Consumption Into the Efficiency Metrics

Under 42 U.S.C. 6295(gg)(2)(A), EPCA requires that standby mode and off mode energy consumption be “integrated into the overall energy efficiency, energy consumption, or other energy descriptor for each covered product” unless the current test procedures already fully account for the standby mode and off mode energy consumption or if such an integrated test procedure is technically infeasible. As noted in the December 2010 NOPR, DOE proposed to incorporate such energy consumption into existing metrics (“estimated annual energy use” and “estimated annual operating cost” for dishwashers and “estimated annual operating cost” for conventional cooking products) and into new metrics (“integrated energy factor” (IEF) for dehumidifiers and IEF and “integrated annual energy consumption” for conventional cooking products). 75 FR 75290, 75316 (Dec. 2, 2010).

EPCA further provides that test procedure amendments adopted to comply with the new statutory requirements for standby mode and off mode energy consumption shall not be used to determine compliance with previously established energy conservation standards. (42 U.S.C. 6295(gg)(2)(C)) Under this provision, the test procedure amendments pertaining to standby mode and off mode energy consumption that DOE proposes to adopt in this rulemaking would not apply to, and would have no impact on, existing energy conservation standards (although representations as to standby mode and off mode energy use for dishwashers, dehumidifiers, and conventional cooking products made later than 180 days after the date of publication of the final rule in this rulemaking would be required to be based upon results generated under the amended test procedures).

Even though 42 U.S.C. 6295(gg)(2)(C) clearly states that the test procedure amendments for measurement of standby mode and off mode energy consumption shall not apply in terms of compliance with existing energy conservation standards, DOE must nonetheless determine the effect of such test procedure amendments on measured energy efficiency, measured energy use, or measured water use of any covered product, pursuant to 42 U.S.C. 6293(e)(1). DOE provided analysis in the December 2010 NOPR which determined that the proposed amendments would not measurably alter the existing energy efficiency and energy use metrics for residential dishwashers, dehumidifiers, and conventional cooking products. In addition, those proposed amendments in each test procedure would clarify that manufacturers would not be required to use the provisions relating to standby mode and off mode energy use until the compliance date of new energy conservation standards addressing such energy use for the relevant product. Thus, no amendments to the energy conservation standards would be required pursuant to 42 U.S.C. 6293(e)(2), because such test procedure amendments would not impact the existing energy conservation standards until the compliance date of a subsequent final rule that amends the standard to comprehensively address standby mode and off mode energy consumption. 75 FR 75290, 75316-17 (Dec. 2, 2010).

Because DOE's proposed amendments in today's SNOPR: (1) Would not produce measurably different evaluations of standby mode and off mode energy use through the use of provisions from IEC Standard 62301 (Second Edition) in place of those from IEC Standard 62301 (First Edition); (2) would not alter the approaches for integrating standby mode and off mode energy use into the energy efficiency and energy use metrics; and (3) would retain the clarifications regarding test procedure and energy conservation standards compliance dates, DOE tentatively concludes that the supplemental proposed amendments would also comply with the EPCA requirements under 42 U.S.C. 6293(e)(2) and 6295(gg)(2)(A) and (C).

4. Certification Requirements

As codified at 42 U.S.C. 6299-6305 and 6316, EPCA authorizes DOE to enforce compliance with the energy and water conservation standards established for certain consumer products and industrial/commercial equipment. (42 U.S.C. 6299-6305 (consumer products), 6316 (industrial equipment)) On March 7, 2011, the Department published a final rule in the Federal Register, which revised, consolidated, and streamlined its existing certification, compliance, and enforcement regulations for certain consumer products and industrial/commercial equipment covered under EPCA, including dishwashers, dehumidifiers, and conventional cooking products. 76 FR 12422. The certification regulations are codified at 10 CFR 429.19 (dishwashers), 10 CFR 429.23 (conventional cooking tops, conventional ovens, microwave ovens), and 10 CFR 429.36 (dehumidifiers).

The certification requirements for each of the products covered in today's SNOPR consist of a sampling plan for selection of units for testing and requirements for certification reports. Because the proposed amendments to the residential dishwasher, dehumidifier, and conventional cooking products test procedures would not revise the current energy conservation standards, DOE is not proposing any amendments to the certification reporting requirements for these products. However, because DOE proposes in today's SNOPR to introduce a new metric (IEF) for both conventional cooking products and dehumidifiers, DOE additionally proposes amended provisions in the sampling plan at 10 CFR 429.23 and 10 CFR 429.36 that would include IEF along with the existing measure of EF. No such amendments are proposed for residential dishwashers, because DOE is not proposing any new energy efficiency metric for these products.

IV. Procedural Issues and Regulatory Review

DOE has concluded that the determinations made pursuant to the various procedural requirements applicable to the December 2010 NOPR remain unchanged for this SNOPR. These determinations are set forth in the December 2010 NOPR. 75 FR 75290, 75317-19 (Dec. 2, 2010). DOE acknowledges that certain provisions of IEC Standard 62301 (Second Edition) that are proposed to be incorporated by reference have the potential for somewhat greater test time as compared to the provisions from IEC Standard 62301 (First Edition), and, therefore, DOE gave particular consideration to its review under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). DOE believes that the proposed amendments in today's SNOPR would still result in a duration of standby mode and off mode testing that is generally not expected to exceed the time required to conduct current energy testing. DOE further believes that the newly proposed revisions would not alter the costs it estimated for standby mode and off mode testing in the December 2010 NOPR. Thus, DOE continues to tentatively conclude and certify that the proposed rule would not have a significant economic impact on a substantial number of small entities. Accordingly, DOE has not prepared a regulatory flexibility analysis for this rulemaking. DOE will transmit the certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 605(b).

B. Issues on Which DOE Seeks Comment

Although comments are welcome on all aspects of this rulemaking, DOE is particularly interested in receiving comments and views of interested parties on the following issues:

1. Incorporation of IEC Standard 62301 (Second Edition). DOE invites comment on the adequacy of IEC Standard 62301 (Second Edition) to measure standby mode and off mode power consumption for residential dishwashers, dehumidifiers, and conventional cooking products, and the suitability of incorporating into DOE regulations the following specific provisions from IEC Standard 62301 (Second Edition): section 4 (“General conditions for measurements”), paragraph 4.2, “Test room,” paragraph 4.3.2, “Supply voltage waveform,” and paragraph 4.4, “Power measuring instruments,” and section 5 (“Measurements”), paragraph 5.1, “General,” paragraph 5.2 “Preparation of product”, and paragraph 5.3.2, “Sampling method.” (See section 0)

2. Methods Based on IEC Standard 62301 (First Edition) for Conventional Cooking Products with Clocks. DOE welcomes comment on its determination that the provisions of IEC Standard 62301 (Second Edition) would cause manufacturers to incur significant test burden for conventional cooking products with power consumption that varies as a function of the time displayed, and the continued proposal of 10-minute and 12-hour test methods of measuring standby mode power for these products in the conventional cooking products test procedure. (See section 0)

3. Test Burden. DOE seeks comment on its analysis of the test burden associated with standby mode and off mode testing as proposed in today's SNOPR. (See sections 0 and 0)

Note:

The procedures and calculations that refer to standby mode and off mode energy consumption (i.e., sections 4.5, 4.5.1 through 4.5.3, and 5.7 of this Appendix C) need not be performed to determine compliance with energy conservation standards for dishwashers at this time. However, any representation related to standby mode and off mode energy consumption of these products made after (date 180 days after date of publication of the test procedure final rule in the Federal Register) must be based upon results generated under this test procedure using sections 4.5, 4.5.1 through 4.5.3, and 5.7 and disregarding sections 4.4 and 5.6 of this Appendix, consistent with the requirements of 42 U.S.C. 6293(c)(2). After July 1, 2010, any adopted energy conservation standard shall incorporate standby mode and off mode energy consumption, and upon the compliance date for such standards, compliance with the applicable provisions of this test procedure will also be required.

1. Definitions

1.1 Active mode means a mode in which the dishwasher is connected to a mains power source, has been activated, and is performing one of the main functions of washing, rinsing, or drying (when a drying process is included) dishware, glassware, eating utensils, and most cooking utensils by chemical, mechanical, and/or electrical means, or is involved in functions necessary for these main functions, such as admitting water into the dishwasher or pumping water out of the dishwasher.

1.2 AHAM means the Association of Home Appliance Manufacturers.

1.3 Compact dishwasher means a dishwasher that has a capacity of less than eight place settings plus six serving pieces as specified in ANSI/AHAM DW-1 (incorporated by reference; see § 430.3), using the test load specified in section 2.7 of this Appendix.

1.4 Cycle means a sequence of operations of a dishwasher which performs a complete dishwashing function, and may include variations or combinations of washing, rinsing, and drying.

1.5 Cycle finished mode means a standby mode which provides continuous status display following operation in active mode.

1.6 Cycle type means any complete sequence of operations capable of being preset on the dishwasher prior to the initiation of machine operation.

1.7 IEC 62301 means the standard published by the International Electrotechnical Commission, titled “Household electrical appliances—Measurement of standby power,” Publication 62301 (Edition 2.0, 2011-01) (incorporated by reference; see § 430.3).

1.8 Inactive mode means a standby mode that facilitates the activation of active mode by remote switch (including remote control), internal sensor, or timer, or that provides continuous status display.

1.9 Non-soil-sensing dishwasher means a dishwasher that does not have the ability to adjust automatically any energy consuming aspect of a wash cycle based on the soil load of the dishes.

1.10 Normal cycle means the cycle type recommended by the manufacturer for completely washing a full load of normally soiled dishes including the power-dry feature.

1.11 Off mode means a mode in which the dishwasher is connected to a mains power source and is not providing any active mode or standby mode function, and where the mode may persist for an indefinite time. An indicator that only shows the user that the product is in the off position is included within the classification of an off mode.

1.12 Power-dry feature means the introduction of electrically-generated heat into the washing chamber for the purpose of improving the drying performance of the dishwasher.

4. Test Cycle and Measurements

* * * * *

4.4 Simplified standby mode power. Connect the dishwasher to a standby wattmeter or a standby watt-hour meter as specified in sections 3.6 and 3.7, respectively, of this Appendix. Select the conditions necessary to achieve operation in the simplified standby mode as defined in section 1.17 of this Appendix. Monitor the power consumption but allow the dishwasher to stabilize for at least 5 minutes. Then monitor the power consumption for at least an additional 5 minutes. If the power level does not change by more than 5 percent from the maximum observed value during the later 5 minutes and if there is no cyclic or pulsing behavior of the load, the load can be considered stable. For stable operation, simplified standby mode power, S_m, can be recorded directly from the standby watt meter in watts or accumulated using the standby watt-hour meter over a period of at least 5 minutes. For unstable operation, the energy must be accumulated using the standby watt-hour meter over a period of at least 5 minutes and must capture the energy use over one or more complete cycles. Calculate the average simplified standby mode power, S_m, expressed in watts by dividing the accumulated energy consumption by the duration of the measurement period.

4.5 Standby mode and off mode power. Connect the dishwasher to a standby mode and off mode watt meter as specified in section 3.8 of this Appendix. Establish the testing conditions set forth in sections 2.1, 2.2, and 2.5.2 of this Appendix. For dishwashers that take some time to enter a stable state from a higher power state as discussed in Section 5, Paragraph 5.1, note 1 of IEC 62301 (incorporated by reference; see § 430.3), allow sufficient time for the dishwasher to reach the lower power state before proceeding with the test measurement. Follow the test procedure specified in Section 5, Paragraph 5.3.2 of IEC 62301 for testing in each possible mode as described in sections 4.5.1 through 4.5.3 of this Appendix.

4.5.1 If the dishwasher has an inactive mode, as defined in section 1.8 of this Appendix, measure and record the average inactive mode power of the dishwasher, P_IA, in watts.

4.5.2 If the dishwasher has an off mode, as defined in section 1.11 of this Appendix, measure and record the average off mode power, P_OM, in watts.

4.5.3 If the dishwasher has a cycle finished mode, as defined in section 1.5 of this Appendix, measure and record the average cycle finished mode power, P_CF, in watts.

5. Calculation of Derived Results From Test Measurements

* * * * *

5.6 Annual simplified standby energy consumption. Calculate the estimated annual simplified standby energy consumption. First determine the number of standby hours per year, H_s, defined as:

H_s = H − (N × L)

Where:

H = the total number of hours per year = 8766 hours per year,

N = the representative average dishwasher use of 215 cycles per year,

L = the average of the duration of the normal cycle and truncated normal cycle, for non-soil-sensing dishwashers with a truncated normal cycle; the duration of the normal cycle, for non-soil-sensing dishwashers without a truncated normal cycle; the average duration of the sensor light response, truncated sensor light response, sensor medium response, truncated sensor medium response, sensor heavy response, and truncated sensor heavy response, for soil-sensing dishwashers with a truncated cycle option; the average duration of the sensor light response, sensor medium response, and sensor heavy response, for soil-sensing dishwashers without a truncated cycle option.

Then calculate the estimated annual simplified standby power use, S, expressed in kilowatt-hours per year and defined as:

S = S_m × ((H_s)/1000)

Where:

S_m = the simplified standby mode power in watts as determined in section 4.4 of this Appendix.

5.7 Annual standby mode and off mode energy consumption. Calculate the standby mode and off mode annual energy consumption for dishwashers, E_TSO, expressed in kilowatt-hours per year, according to the following:

E_TSO = [(P_IA × S_IA) + (P_OM × S_OM) + (P_CF × S_CF)] × K

Where:

P_IA= dishwasher inactive mode power, in watts, as measured in section 4.5.1 of this Appendix.

P_OM = dishwasher off mode power, in watts, as measured in section 4.5.2 of this Appendix.

P_CF = dishwasher cycle finished mode power, in watts, as measured in section 4.5.3 of this Appendix.

If the dishwasher has both inactive mode and off mode, S_IA and S_OM both equal S_TOT/2;

S_TOT equals the total number of inactive mode and off mode hours per year, defined as:

If the dishwasher has cycle finished mode, S_TOT, in hours, equals H_TSO − S_CF;

If the dishwasher does not have cycle finished mode, S_TOT equals H_TSO;

H_TSO equals the total number of standby mode and off mode hours per year, defined as:

H_TSO = H − (N × L)

Where:

H = the total number of hours per year = 8766 hours per year,

N = the representative average dishwasher use of 215 cycles per year,

L = the average of the duration of the normal cycle and truncated normal cycle, for non-soil-sensing dishwashers with a truncated normal cycle; the duration of the normal cycle, for non-soil-sensing dishwashers without a truncated normal cycle; the average duration of the sensor light response, truncated sensor light response, sensor medium response, truncated sensor medium response, sensor heavy response, and truncated sensor heavy response, for soil-sensing dishwashers with a truncated cycle option; the average duration of the sensor light response, sensor medium response, and sensor heavy response, for soil-sensing dishwashers without a truncated cycle option;

If the dishwasher has an inactive mode but no off mode, the inactive mode annual hours, S_IA, is equal to S_TOT, and the off mode annual hours, S_OM, is equal to 0;

If the dishwasher has an off mode but no inactive mode, S_IA is equal to 0, and S_OM is equal to S_TOT;

S_CF = 237, dishwasher cycle finished mode annual hours;

K = 0.001 kWh/Wh conversion factor for watt-hours to kilowatt-hours.

Appendix I to Subpart B of Part 430—Uniform Test Method for Measuring the Energy Consumption of Conventional Ranges, Conventional Cooking Tops, Conventional Ovens, and Microwave Ovens

Note:

The procedures and calculations in this Appendix I need not be performed to determine compliance with energy conservation standards for conventional ranges, conventional cooking tops, conventional ovens, and microwave ovens at this time. However, any representation related to standby mode and off mode energy consumption of conventional ranges, conventional cooking tops, and conventional ovens made after (date 180 days after date of publication of the test procedure final rule in the Federal Register) and of microwave ovens made after September 6, 2011 must be based upon results generated under this test procedure, consistent with the requirements of 42 U.S.C. 6293(c)(2). After July 1, 2010, however, when DOE adopts an energy conservation standard that incorporates standby mode and off mode energy consumption, and upon the compliance date for such standards, compliance with the applicable provisions of this test procedure will also be required. Future revisions may add relevant provisions for measuring active mode in microwave ovens.

1. Definitions

1.1 Active mode means a mode in which the product is connected to a mains power source, has been activated, and is performing the main function of producing heat by means of a gas flame, electric resistance heating, or microwave energy. Delay start mode is a one-off, user-initiated, short-duration function that is associated with an active mode.

1.2 Built-in means the product is supported by surrounding cabinetry, walls, or other similar structures.

1.3 Cycle finished mode means a standby mode in which a conventional cooking top, conventional oven, or conventional range provides continuous status display following operation in active mode.

1.4 Drop-in means the product is supported by horizontal surface cabinetry.

1.5 Forced convection means a mode of conventional oven operation in which a fan is used to circulate the heated air within the oven compartment during cooking.

1.6 Freestanding means the product is not supported by surrounding cabinetry, walls, or other similar structures.

1.7 IEC 62301 First Edition means the test standard published by the International Electrotechnical Commission, titled “Household electrical appliances—Measurement of standby power,” Publication 62301 (First Edition 2005-06) (incorporated by reference; see § 430.3).

1.8 IEC 62301 Second Edition means the test standard published by the International Electrotechnical Commission, titled “Household electrical appliances—Measurement of standby power,” Publication 62301 (Edition 2.0 2011-01) (incorporated by reference; see § 430.3).

1.9 Inactive mode means a standby mode that facilitates the activation of active mode by remote switch (including remote control), internal sensor, or timer, or that provides continuous status display.

1.10 Normal nonoperating temperature means the temperature of all areas of an appliance to be tested are within 5 °F (2.8 °C) of the temperature that the identical areas of the same basic model of the appliance would attain if it remained in the test room for 24 hours while not operating with all oven doors closed and with any gas pilot lights on and adjusted in accordance with manufacturer's instructions.

1.11 Off mode means a mode in which the product is connected to a mains power source and is not providing any active mode or standby mode function, and where the mode may persist for an indefinite time. An indicator that only shows the user that the product is in the off position is included within the classification of an off mode.

1.12 Primary energy consumption means either the electrical energy consumption of a conventional electric oven or the gas energy consumption of a conventional gas oven.

1.13 Secondary energy consumption means any electrical energy consumption of a conventional gas oven.

1.14 Standard cubic foot (L) of gas means that quantity of gas that occupies 1 cubic foot (L) when saturated with water vapor at a temperature of 60 °F (15.6 °C) and a pressure of 30 inches of mercury (101.6 kPa) (density of mercury equals 13.595 grams per cubic centimeter).

6. Appendix X to subpart B of part 430 is revised to read as follows:

Appendix X to Subpart B of Part 430—Uniform Test Method for Measuring the Energy Consumption of Dehumidifiers

Note:

The procedures and calculations that refer to standby mode and off mode energy consumption (i.e., sections 3.2, 3.2.1 through 3.2.4, 4.2, 4.2.1 through 4.2.4, 5.1, and 5.2 of this Appendix X) need not be performed to determine compliance with energy conservation standards for dehumidifiers at this time. However, any representation related to standby mode and off mode energy consumption of these products made after (date 180 days after date of publication of the test procedure final rule in the Federal Register) must be based upon results generated under this test procedure, consistent with the requirements of 42 U.S.C. 6293(c)(2). After July 1, 2010, any adopted energy conservation standard shall incorporate standby mode and off mode energy consumption, and upon the compliance date for such standards, compliance with the applicable provisions of this test procedure will also be required.

1. Scope

This Appendix covers the test requirements used to measure the energy performance of dehumidifiers.

2. Definitions

a. Active mode means a mode in which a dehumidifier is connected to a mains power source, has been activated, and is performing the main functions of removing moisture from air by drawing moist air over a refrigerated coil using a fan, or circulating air through activation of the fan without activation of the refrigeration system.

b. Bucket full/removed mode means a standby mode in which the dehumidifier has automatically powered off its main function by detecting when the water bucket is full or has been removed.

c. Energy factor for dehumidifiers means a measure of energy efficiency of a dehumidifier calculated by dividing the water removed from the air by the energy consumed, measured in liters per kilowatt-hour (L/kWh).

d. IEC 62301 means the test standard published by the International Electrotechnical Commission, titled “Household electrical appliances—Measurement of standby power,” Publication 62301 (Edition 2.0 2011-01) (incorporated by reference; see § 430.3).

e. Inactive mode means a standby mode that facilitates the activation of active mode by remote switch (including remote control), internal sensor, or timer, or that provides continuous status display.

f. Off mode means a mode in which the dehumidifier is connected to a mains power source and is not providing any active mode or standby mode function, and where the mode may persist for an indefinite time. An indicator that only shows the user that the dehumidifier is in the off position is included within the classification of an off mode.

g. Off-cycle mode means a standby mode in which the dehumidifier:

(1) Has cycled off its main function by humidistat or humidity sensor;

(2) Does not have its fan or blower operating; and

(3) Will reactivate the main function according to the humidistat or humidity sensor signal.

h. Product capacity for dehumidifiers means a measure of the ability of the dehumidifier to remove moisture from its surrounding atmosphere, measured in pints collected per 24 hours of continuous operation.

i. Standby mode means any modes where the dehumidifier is connected to a mains power source and offers one or more of the following user-oriented or protective functions which may persist for an indefinite time:

(1) To facilitate the activation of other modes (including activation or deactivation of active mode) by remote switch (including remote control), internal sensor, or timer;

(2) Continuous functions, including information or status displays (including clocks) or sensor-based functions. A timer is a continuous clock function (which may or may not be associated with a display) that provides regular scheduled tasks (e.g., switching) and that operates on a continuous basis.

3. Test Apparatus and General Instructions

3.1 Active mode. The test apparatus and instructions for testing dehumidifiers shall conform to the requirements specified in Section 1, “Definitions,” Section 2, “Qualifying Products,” and Section 4, “Test Criteria,” of the EPA's “ENERGY STAR Program Requirements for Dehumidifiers,” effective January 1, 2001 (incorporated by reference, see § 430.3). Record measurements at the resolution of the test instrumentation. Round off calculations to the same number of significant digits as the previous step. Round the final minimum energy factor value to two decimal places as follows:

(i) A fractional number at or above the midpoint between two consecutive decimal places shall be rounded up to the higher of the two decimal places; or

(ii) A fractional number below the midpoint between two consecutive decimal places shall be rounded down to the lower of the two decimal places.

3.2 Standby mode and off mode.

3.2.1 Installation requirements. For the standby mode and off mode testing, the dehumidifier shall be installed in accordance with Section 5, Paragraph 5.2 of IEC 62301 (incorporated by reference, see § 430.3), disregarding the provisions regarding batteries and the determination, classification, and testing of relevant modes.

3.2.2 Electrical energy supply.

For dehumidifiers that take some time to enter a stable state from a higher power state as discussed in Section 5, Paragraph 5.1, Note 1 of IEC 62301, (incorporated by reference; see § 430.3), allow sufficient time for the dehumidifier to reach the lower power state before proceeding with the test measurement. Follow the test procedure specified in Section 5, Paragraph 5.3.2 of IEC 62301 for testing in each possible mode as described in sections 4.2.1 through 4.2.4 of this Appendix.
