Federal Register / Vol. 86, No. 194 / Tuesday, October 12, 2021 / Rules and Regulations
2 Compartment temperatures used to determine product category shall be the mean of the measured compartment temperatures at the coldest setting for each tested unit of the basic model according to the provisions of appendix A to subpart B of part 430 of this chapter. For cooler compartments with temperatures below 39 F 3.9 C but no lower than 37 F 2.8 C, the compartment temperatures used to determine product category shall also include the mean of the measured compartment temperatures at the warmest setting for each tested unit of the basic model according to the provisions of appendix A to subpart B
of part 430 of this chapter.
4. Section 429.134 is amended by revising paragraphs b2 and l2 to read as follows:
429.134 Product-specific enforcement provisions.

2 Test for models with two compartments, each having its own user-operable temperature control. The test described in section 5.2b of the applicable test procedure for refrigerators or refrigerator-freezers in appendix A to subpart B of 10 CFR part 430 shall be used for all units of a tested basic model before DOE makes a determination of noncompliance with respect to the basic model.

l
2 Test for models with two compartments, each having its own user-operable temperature control. The test described in section 5.2b of the applicable test procedure in appendix A
to subpart B part 430 of this chapter shall be used for all units of a tested basic model before DOE makes a determination of noncompliance with respect to the basic model.
