§ 86.1009-97 - Calculation and reporting of test results.

Section 86.1009-97 includes text that specifies requirements that differ from those specified in §§ 86.1009-84 and 86.1009-96. Where a paragraph in § 86.1009-84 or § 86.1009-96 is identical and applicable to § 86.1009-97, this may be indicated by specifying the corresponding paragraph and the statement “[Reserved].

(a) and (b) [Reserved]. For guidance see § 86.1009-96.

(c) Final deteriorated test results. (1) The final deteriorated test results for each heavy-duty engine or light-duty truck tested according to subpart B, C, D, I, N, P, or R of this part are calculated by first multiplying or adding, as appropriate, the final test results by or to the appropriate deterioration factor derived from the certification process for the engine family control system combination and model year to which the selected configuration belongs, and then by multiplying by the appropriate reactivity adjustment factor, if applicable. If the multiplicative deterioration factor as computed during the certification process is less than one, that deterioration factor will be one. If the additive deterioration factor as computed during the certification process is less than zero, that deterioration factor will be zero.

(c)(2) [Reserved]

(c)(3) through (c)(4) [Reserved]. For guidance see § 86.1009-96.
