1. Definitions

Active mode means a mode in which the clothes washer is connected to a mains power source, has been activated, and is performing one or more of the main functions of washing, soaking, tumbling, agitating, rinsing, and/or removing water from the clothing, or is involved in functions necessary for these main functions, such as admitting water into the washer or pumping water out of the washer. Active mode also includes delay start and cycle finished modes.

Active-mode energy efficiency ratio means the quotient of the weighted-average load size divided by the total clothes washer energy consumption per cycle, with such energy consumption expressed as the sum of the machine electrical energy consumption, the hot water energy consumption, and the energy required for removal of the remaining moisture in the wash load.

Active washing mode means a mode in which the clothes washer is performing any of the operations included in a complete cycle intended for washing a clothing load, including the main functions of washing, soaking, tumbling, agitating, rinsing, and/or removing water from the clothing.

Bone-dry means a condition of a load of test cloth that has been dried in a dryer at maximum temperature for a minimum of 10 minutes, removed and weighed before cool down, and then dried again for 10 minute periods until the final weight change of the load is 1 percent or less.

Clothes container means the compartment within the clothes washer that holds the clothes during the operation of the machine.

Cold rinse means the coldest rinse temperature available on the machine, as indicated to the user on the clothes washer control panel.

Combined low-power mode means the aggregate of available modes other than active washing mode, including inactive mode, off mode, delay start mode, and cycle finished mode.

Cycle finished mode means an active mode that provides continuous status display, intermittent tumbling, or air circulation following operation in active washing mode.

Delay start mode means an active mode in which activation of active washing mode is facilitated by a timer.

Energy efficiency ratio means the quotient of the weighted-average load size divided by the total clothes washer energy consumption per cycle, with such energy consumption expressed as the sum of:

(a) The machine electrical energy consumption;

(b) The hot water energy consumption;

(c) The energy required for removal of the remaining moisture in the wash load; and

(d) The combined low-power mode energy consumption.

Energy test cycle means the complete set of wash/rinse temperature selections required for testing, as determined according to section 2.12 of this appendix.

Fixed water fill control system means a clothes washer water fill control system that automatically terminates the fill when the water reaches a pre-defined level that is not based on the size or weight of the clothes load placed in the clothes container, without allowing or requiring the user to determine or select the water fill level.

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.

Load usage factor means the percentage of the total number of wash loads that a user would wash a particular size (weight) load.

Lot means a quantity of cloth that has been manufactured with the same batches of cotton and polyester during one continuous process.

Manual water fill control system means a clothes washer water fill control system that requires the user to determine or select the water fill level.

Normal cycle means the cycle recommended by the manufacturer (considering manufacturer instructions, control panel labeling, and other markings on the clothes washer) for normal, regular, or typical use for washing up to a full load of normally soiled cotton clothing. For machines where multiple cycle settings are recommended by the manufacturer for normal, regular, or typical use for washing up to a full load of normally soiled cotton clothing, then the Normal cycle is the cycle selection that results in the lowest EER or AEER value.

Off mode means a mode in which the clothes washer is connected to a mains power source and is not providing any active or standby mode function, and where the mode may persist for an indefinite time.

Standby mode means any mode in which the clothes washer is connected to a mains power source and offers one or more of the following user oriented or protective functions that may persist for an indefinite time:

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

(b) 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.

Temperature use factor means, for a particular wash/rinse temperature setting, the percentage of the total number of wash loads that an average user would wash with that setting.

User-adjustable adaptive water fill control system means a clothes washer fill control system that allows the user to adjust the amount of water that the machine provides, which is based on the size or weight of the clothes load placed in the clothes container.

2. Testing Conditions and Instrumentation

2.1 Electrical energy supply.

2.1.1 Supply voltage and frequency. Maintain the electrical supply at the clothes washer terminal block within 2 percent of 120, 120/240, or 120/208Y volts as applicable to the particular terminal block wiring system and within 2 percent of the nameplate frequency as specified by the manufacturer. If the clothes washer has a dual voltage conversion capability, conduct test at the highest voltage specified by the manufacturer.

2.1.2 Supply voltage waveform. For the combined low-power mode testing, maintain the electrical supply voltage waveform indicated in Section 4, Paragraph 4.3.2 of IEC 62301. If the power measuring instrument used for testing is unable to measure and record the total harmonic content during the test measurement period, total harmonic content may be measured and recorded immediately before and after the test measurement period.

2.2 Supply water. Maintain the temperature of the hot water supply at the water inlets between 120 °F (48.9 °C) and 125 °F (51.7 °C), targeting the midpoint of the range. Maintain the temperature of the cold water supply at the water inlets between 55 °F (12.8 °C) and 60 °F (15.6 °C), targeting the midpoint of the range.

2.3 Water pressure. Maintain the static water pressure at the hot and cold water inlet connection of the clothes washer at 35 pounds per square inch gauge (psig) ± 2.5 psig (241.3 kPa ± 17.2 kPa) when the water is flowing.

2.4 Test room temperature. For all clothes washers, maintain the test room ambient air temperature at 75 ± 5 °F (23.9 ± 2.8 °C) for active mode testing and combined low-power mode testing. Do not use the test room ambient air temperature conditions specified in Section 4, Paragraph 4.2 of IEC 62301 for combined low-power mode testing.

2.5 Instrumentation. Perform all test measurements using the following instruments, as appropriate:

2.5.1 Weighing scales.

2.5.1.1 Weighing scale for test cloth. The scale used for weighing test cloth must have a resolution of no larger than 0.2 oz (5.7 g) and a maximum error no greater than 0.3 percent of the measured value.

2.5.1.2 Weighing scale for clothes container capacity measurement. The scale used for performing the clothes container capacity measurement must have a resolution no larger than 0.50 lbs (0.23 kg) and a maximum error no greater than 0.5 percent of the measured value.

2.5.2 Watt-hour meter. The watt-hour meter used to measure electrical energy consumption must have a resolution no larger than 1 Wh (3.6 kJ) and a maximum error no greater than 2 percent of the measured value for any demand greater than 50 Wh (180.0 kJ).

2.5.3 Watt meter. The watt meter used to measure combined low-power mode power consumption must comply with the requirements specified in Section 4, Paragraph 4.4 of IEC 62301. If the power measuring instrument used for testing is unable to measure and record the crest factor, power factor, or maximum current ratio during the test measurement period, the crest factor, power factor, and maximum current ratio may be measured and recorded immediately before and after the test measurement period.

2.5.4 Water and air temperature measuring devices. The temperature devices used to measure water and air temperature must have an error no greater than ±1 °F (±0.6 °C) over the range being measured.

2.5.4.1 Non-reversible temperature indicator labels, adhered to the inside of the clothes container, may be used to confirm that an extra-hot wash temperature greater than or equal to 140 °F has been achieved during the wash cycle, under the following conditions. The label must remain waterproof, intact, and adhered to the wash drum throughout an entire wash cycle; provide consistent maximum temperature readings; and provide repeatable temperature indications sufficient to demonstrate that a wash temperature of greater than or equal to 140 °F has been achieved. The label must have been verified to consistently indicate temperature measurements with an accuracy of ±1 °F. If using a temperature indicator label to test a front-loading clothes washer, adhere the label along the interior surface of the clothes container drum, midway between the front and the back of the drum, adjacent to one of the baffles. If using a temperature indicator label to test a top-loading clothes washer, adhere the label along the interior surface of the clothes container drum, on the vertical portion of the sidewall, as close to the bottom of the container as possible.

2.5.4.2 Submersible temperature loggers placed inside the wash drum may be used to confirm that an extra-hot wash temperature greater than or equal to 140 °F has been achieved during the wash cycle, under the following conditions. The submersible temperature logger must have a time resolution of at least 1 data point every 5 seconds and a temperature measurement accuracy of ±1 °F. Due to the potential for a waterproof capsule to provide a thermal insulating effect, failure to measure a temperature of 140 °F does not necessarily indicate the lack of an extra-hot wash temperature. However, such a result would not be conclusive due to the lack of verification of the water temperature requirement, in which case an alternative method must be used to confirm that an extra-hot wash temperature greater than or equal to 140 °F has been achieved during the wash cycle.

2.5.5 Water meter. A water meter must be installed in both the hot and cold water lines to measure water flow and/or water consumption. The water meters must have a resolution no larger than 0.1 gallons (0.4 liters) and a maximum error no greater than 2 percent for the water flow rates being measured. If the volume of hot water for any individual cycle within the energy test cycle is less than 0.1 gallons (0.4 liters), the hot water meter must have a resolution no larger than 0.01 gallons (0.04 liters).

2.5.6 Water pressure gauge. A water pressure gauge must be installed in both the hot and cold water lines to measure water pressure. The water pressure gauges must have a resolution of 1 pound per square inch gauge (psig) (6.9 kPa) and a maximum error no greater than 5 percent of any measured value.

2.6 Bone-dryer. The dryer used for drying the cloth to bone-dry must heat the test cloth load above 210 °F (99 °C).

2.7 Test cloths. The test cloth material and dimensions must conform to the specifications in appendix J3 to this subpart. The energy test cloth and the energy stuffer cloths must be clean and must not be used for more than 60 test runs (after preconditioning as specified in section 5 of appendix J3 to this subpart). All energy test cloth must be permanently marked identifying the lot number of the material. Mixed lots of material must not be used for testing a clothes washer. The moisture absorption and retention must be evaluated for each new lot of test cloth using the standard extractor Remaining Moisture Content (RMC) procedure specified in appendix J3 to this subpart.

2.8 Test Loads.

2.8.1 Test load sizes. Create small and large test loads as defined in Table 5.1 of this appendix based on the clothes container capacity as measured in section 3.1 of this appendix. Record the bone-dry weight for each test load.

2.8.2 Test load composition. Test loads must consist primarily of energy test cloths and no more than five energy stuffer cloths per load to achieve the proper weight.

2.9 Preparation and loading of test loads. Use the following procedures to prepare and load each test load for testing in section 3 of this appendix.

2.9.1 Test loads for energy and water consumption measurements must be bone-dry prior to the first cycle of the test, and dried to a maximum of 104 percent of bone-dry weight for subsequent testing.

2.9.2 Prepare the energy test cloths for loading by grasping them in the center, lifting, and shaking them to hang loosely, as illustrated in Figure 2.9.2 of this appendix.

For all clothes washers, follow any manufacturer loading instructions provided to the user regarding the placement of clothing within the clothes container. In the absence of any manufacturer instructions regarding the placement of clothing within the clothes container, the following loading instructions apply.

2.9.2.1 To load the energy test cloths in a top-loading clothes washer, arrange the cloths circumferentially around the axis of rotation of the clothes container, using alternating lengthwise orientations for adjacent pieces of cloth. Complete each cloth layer across its horizontal plane within the clothes container before adding a new layer. Figure 2.9.2.1 of this appendix illustrates the correct loading technique for a vertical-axis clothes washer.

2.9.2.2 To load the energy test cloths in a front-loading clothes washer, grasp each test cloth in the center as indicted in section 2.9.2 of this appendix, and then place each cloth into the clothes container prior to activating the clothes washer.

2.10 Clothes washer installation. Install the clothes washer in accordance with manufacturer's instructions.

2.10.1 Water inlet connections. If the clothes washer has 2 water inlets, connect the inlets to the hot water and cold water supplies, in accordance with the manufacturer's instructions. If the clothes washer has only 1 water inlet, connect the inlet to the cold water supply, in accordance with the manufacturer's instructions. Use the water inlet hoses provided with the clothes washer; otherwise use commercially available water inlet hoses, not to exceed 72 inches in length, in accordance with manufacturer's instructions.

2.10.2 Low-power mode testing. For combined low-power mode testing, install the clothes washer in accordance with Section 5, Paragraph 5.2 of IEC 62301, disregarding the provisions regarding batteries and the determination, classification, and testing of relevant modes.

2.11 Clothes washer pre-conditioning. If the clothes washer has not been filled with water in the preceding 96 hours, or if it has not been in the test room at the specified ambient conditions for 8 hours, pre-condition it by running it through a cold rinse cycle and then draining it to ensure that the hose, pump, and sump are filled with water.

2.12 Determining the energy test cycle .

2.12.1 Automatic clothes washers. To determine the energy test cycle, evaluate the wash/rinse temperature selection flowcharts in the order in which they are presented in this section. Use the large load size to evaluate each flowchart. The determination of the energy test cycle must take into consideration all cycle settings available to the end user, including any cycle selections or cycle modifications provided by the manufacturer via software or firmware updates to the product, for the basic model under test. The energy test cycle does not include any cycle that is recommended by the manufacturer exclusively for cleaning, deodorizing, or sanitizing the clothes washer.

2.12.2. Semi-automatic clothes washers. The energy test cycle for semi-automatic clothes washers includes only the Cold Wash/Cold Rinse (“Cold”) test cycle. Energy and water use for all other wash/rinse temperature combinations are calculated numerically in section 3.4.2 of this appendix.

3. Test Measurements

3.1 Clothes container capacity. Measure the entire volume that a clothes load could occupy within the clothes container during active mode washer operation according to the following procedures:

3.1.1 Place the clothes washer in such a position that the uppermost edge of the clothes container opening is leveled horizontally, so that the container will hold the maximum amount of water. For front-loading clothes washers, the door seal and shipping bolts or other forms of bracing hardware to support the wash drum during shipping must remain in place during the capacity measurement. If the design of a front-loading clothes washer does not include shipping bolts or other forms of bracing hardware to support the wash drum during shipping, a laboratory may support the wash drum by other means, including temporary bracing or support beams. Any temporary bracing or support beams must keep the wash drum in a fixed position, relative to the geometry of the door and door seal components, that is representative of the position of the wash drum during normal operation. The method used must avoid damage to the unit that would affect the results of the energy and water testing. For a front-loading clothes washer that does not include shipping bolts or other forms of bracing hardware to support the wash drum during shipping, the laboratory must fully document the alternative method used to support the wash drum during capacity measurement, include such documentation in the final test report, and pursuant to § 429.71 of this chapter, the manufacturer must retain such documentation as part its test records.

3.1.2 Line the inside of the clothes container with a 2 mil thickness (0.051 mm) plastic bag. All clothes washer components that occupy space within the clothes container and that are recommended for use during a wash cycle must be in place and must be lined with a 2 mil thickness (0.051 mm) plastic bag to prevent water from entering any void space.

3.1.3 Record the total weight of the machine before adding water.

3.1.4 Fill the clothes container manually with either 60 °F ± 5 °F (15.6 °C ± 2.8 °C) or 100 °F ± 10 °F (37.8 °C ± 5.5 °C) water, with the door open. For a top-loading vertical-axis clothes washer, fill the clothes container to the uppermost edge of the rotating portion, including any balance ring. Figure 3.1.4.1 of this appendix illustrates the maximum fill level for top-loading clothes washers.

For a front-loading horizontal-axis clothes washer, fill the clothes container to the highest point of contact between the door and the door gasket. If any portion of the door or gasket would occupy the measured volume space when the door is closed, exclude from the measurement the volume that the door or gasket portion would occupy. For a front-loading horizontal-axis clothes washer with a concave door shape, include any additional volume above the plane defined by the highest point of contact between the door and the door gasket, if that area can be occupied by clothing during washer operation. For a top-loading horizontal-axis clothes washer, include any additional volume above the plane of the door hinge that clothing could occupy during washer operation. Figure 3.1.4.2 of this appendix illustrates the maximum fill volumes for all horizontal-axis clothes washer types.

For all clothes washers, exclude any volume that cannot be occupied by the clothing load during operation.

3.1.5 Measure and record the weight of water, W, in pounds.

3.1.6 Calculate the clothes container capacity as follows:

C = W/d

Where:

C = Capacity in cubic feet (liters).

W = Mass of water in pounds (kilograms).

d = Density of water (62.0 lbs/ft³ for 100 °F (993 kg/m³ for 37.8 °C) or 62.3 lbs/ft³ for 60 °F (998 kg/m³ for 15.6 °C)).

3.1.7 Calculate the clothes container capacity, C, to the nearest 0.01 cubic foot for the purpose of determining test load sizes per Table 5.1 of this appendix and for all subsequent calculations that include the clothes container capacity.

3.2 Cycle settings.

3.2.1 Wash/rinse temperature selection. For automatic clothes washers, set the wash/rinse temperature selection control to obtain the desired wash/rinse temperature selection within the energy test cycle.

3.2.2 Wash time setting.

3.2.2.1 If the cycle under test offers a range of wash time settings, the wash time setting shall be the higher of either the minimum or 70 percent of the maximum wash time available for the wash cycle under test, regardless of the labeling of suggested dial locations. If 70 percent of the maximum wash time is not available on a dial with a discrete number of wash time settings, choose the next-highest setting greater than 70 percent.

3.2.2.2 If the clothes washer is equipped with an electromechanical dial or timer controlling wash time that rotates in both directions, reset the dial to the minimum wash time and then turn it in the direction of increasing wash time to reach the appropriate setting. If the appropriate setting is passed, return the dial to the minimum wash time and then turn in the direction of increasing wash time until the appropriate setting is reached.

3.2.3 Water fill level settings. The water fill level settings depend on the clothes washer's water fill control system, as determined in Table 3.2.3.

Table 3.2.3 - Clothes Washer Water Fill Control Settings

	Settings are user-adjustable	Settings are not user-adjustable
Water fill level unaffected by the size or weight of the clothing load	Manual water fill	Fixed water fill.
Water fill level is determined automatically by the clothes washer based on the size and weight of the clothing load	User-adjustable adaptive water fill	Non-user-adjustable adaptive water fill.

3.2.3.1 Clothes washers with a manual water fill control system. For the large test load size, set the water fill level selector to the maximum water fill level setting available for the wash cycle under test. If the water fill level selector has two settings available for the wash cycle under test, for the small test load size, select the minimum water fill level setting available for the wash cycle under test.

If the water fill level selector has more than two settings available for the wash cycle under test, for the small test load size, select the second-lowest water fill level setting.

3.2.3.2 Clothes washers with a fixed water fill control system. The water level is automatically determined by the water fill control system.

3.2.3.3 Clothes washers with a user-adjustable adaptive water fill control system. For the large test load size, set the water fill selector to the setting that uses the most water. For the small test load size, set the water fill selector to the setting that uses the least water.

3.2.3.4 Clothes washers with a non-user-adjustable adaptive water fill control system. The water level is automatically determined by the water fill control system.

3.2.3.5 Clothes washers with multiple water fill control systems. If a clothes washer allows user selection among multiple water fill control systems, test all water fill control systems and, for each one, calculate the energy consumption (HE_T, ME_T, and DE_T) and water consumption (Q_T) values as set forth in section 4 of this appendix. Then, calculate the average of the tested values (one from each water fill control system) for each variable (HE_T, ME_T, DE_T, and Q_T) and use the average value for each variable in the final calculations in section 4 of this appendix.

3.2.4 Manufacturer default settings. For clothes washers with electronic control systems, use the manufacturer default settings for any cycle selections, except for

(1) the temperature selection,

(2) the wash water fill levels, or

(3) network settings. If the clothes washer has network capabilities, the network settings must be disabled throughout testing if such settings can be disabled by the end-user and the product's user manual provides instructions on how to do so. For all other cycle selections, the manufacturer default settings must be used for wash conditions such as agitation/tumble operation, soil level, spin speed, wash times, rinse times, optional rinse settings, water heating time for water heating clothes washers, and all other wash parameters or optional features applicable to that wash cycle. Any optional wash cycle feature or setting (other than wash/rinse temperature, water fill level selection, or network settings on clothes washers with network capabilities) that is activated by default on the wash cycle under test must be included for testing unless the manufacturer instructions recommend not selecting this option, or recommend selecting a different option, for washing normally soiled cotton clothing. For clothes washers with control panels containing mechanical switches or dials, any optional settings, except for the temperature selection or the wash water fill levels, must be in the position recommended by the manufacturer for washing normally soiled cotton clothing. If the manufacturer instructions do not recommend a particular switch or dial position to be used for washing normally soiled cotton clothing, the setting switch or dial must remain in its as-shipped position.

3.2.5 For each wash cycle tested, include the entire active washing mode and exclude any delay start or cycle finished modes.

3.2.6 Anomalous Test Cycles. If during a wash cycle the clothes washer: (a) Signals to the user by means of a visual or audio alert that an out-of-balance condition has been detected; or (b) terminates prematurely and thus does not include the agitation/tumble operation, spin speed(s), wash times, and rinse times applicable to the wash cycle under test, discard the test data and repeat the wash cycle. Document in the test report the rejection of data from any wash cycle during testing and the reason for the rejection.

3.3 Test cycles for automatic clothes washers. Perform testing on each wash/rinse temperature selection available in the energy test cycle was defined in section 2.12.1 of this appendix. Test each load size as defined in section 2.8 of this appendix with its associated water fill level defined in section 3.2.3 of this appendix. Assign the bone-dry weight according to the value measured in section 2.8 of this appendix. Place the test load in the clothes washer and initiate the cycle under test. Measure the values for hot water consumption, cold water consumption, electrical energy consumption, and cycle time for the complete cycle. Record the weight of the test load immediately after completion of the cycle. Table 3.3 of this appendix provides the symbol definitions for each measured value.

* If two cycles are tested to represent the Warm/Cold selection or the Warm/Warm selection, calculate the average of the two tested cycles and use that value for all further calculations.

3.4 Test cycles for semi-automatic clothes washers.

3.4.1 Test Measurements. Perform testing on each wash/rinse temperature selection available in the energy test cycle as defined in section 2.12.2 of this appendix. Test each load size as defined in section 2.8 of this appendix with the associated water fill level defined in section 3.2.3 of this appendix. Assign the bone-dry weight according to the value measured in section 2.8 of this appendix. Place the test load in the clothes washer and initiate the cycle under test. Measure the values for cold water consumption, electrical energy consumption, and cycle time for the complete cycle. Record the weight of the test load immediately after completion of the cycle. Table 3.4.1 of this appendix provides symbol definitions for each measured value for the Cold temperature selection.
