Federal Register / Vol. 86, No. 193 / Friday, October 8, 2021 / Rules and Regulations to the prior test procedure. Therefore, the amendment regarding network capabilities adopted in this final rule will not result in a basic model that is complaint under the prior test procedure becoming non-compliant.
DOE provides additional direction on the dryness level setting for clothes dryers that provide an even number of discrete dryness settings. This amendment impacts only appendix D2, and therefore has no impact on testing under appendix D1. This amendment will not impact testing costs, as it provides direction for the required setting for the previously required test, without requiring any additional testing.
DOE is updating the representative annual number of drying cycles in the per-cycle standby mode and off mode energy consumption calculations in appendix D2 to use the most recently available data. The updated number of drying cycles will not be required for use unless and until such time the energy conservation standards are amended taking into account the updated value. As such, this amendment will not require retesting or recertification.
DOE provides revisions regarding the measurement and accounting of standby mode and off mode power in both appendix D1 and appendix D2. DOE has determined that these revisions potentially reduce testing costs for third-party laboratories, as the amendment does not require any disassembly of a clothes dryer to determine the appropriate application of the test procedure. However, DOE has not quantified the potential reduction in testing cost.
DOE provides a variety of formatting and typographical corrections to both appendix D1 and appendix D2. These edits remove confusion that may result from the errors and improve the readability of the test procedures.
DOE amends 10 CFR 430.23d to include instructions for calculating estimated annual operating cost, CEF, and other useful metrics using appendix D2. The prior test procedure provision provided for the calculation of these values using measurements from appendix D1. The test procedure as finalized in this document also explicitly provides for calculating these values using measurements from appendix D2. This amendment provides additional direction regarding the calculation of metrics and no additional testing will be required.
DOE is revising the required weighing scale resolution for weighing test cloths to limit test variation consistent with current test laboratory capabilities. In DOEs experience, testing facilities are

currently using instrumentation that meet these new instrumentation requirements, and therefore DOE
concludes that these revisions will not impact test burden.
Manufacturers will be able to rely on data generated under the previous test procedure, and no retesting or recertification will be required as a result of this test procedure.
H. Harmonization With Industry Standards The test procedures for clothes dryers in appendix D1 and appendix D2
incorporate by reference AHAM HLD
12009, Household Tumble Type Clothes Dryers, which was later certified as ANSI/AHAM HLD12010
and IEC Standard 62301. Specifically, both appendices reference an exhaust simulator specified in AHAM HLD1
2009 in their test setup instructions, and incorporate IEC Standard 62301, which provides test conditions, testing equipment, and methods for measuring standby mode and off mode power consumption. Appendix D1 and appendix D2 also require the use of AHAM Standard Test Detergent Formula 3 for preconditioning the test cloths. DOE has determined that the revisions to the standby and off mode power provisions do not impact the existing references to industry standards and do not alter the applicability of those referenced industry standards to the DOE test procedure.
The California IOUs suggested that DOE review comments they submitted in response to the NOPR published on February 13, 2019, proposing amendments to DOEs rulemaking process 84 FR 3910; specifically, their recommendation that DOE use industrybased test procedures as guidance documents and that all industry test procedures should be evaluated consistent with EPCA. California IOUs, No. 29 at p. 21 AHAM supported the practice of adopting voluntary consensus-based test procedures without modification, specifically the incorporation by reference of the latest version of AHAM HLD1, though AHAM did not support incorporation by reference of IEC Standard 61121. AHAM
commented that, while there may be times when it is appropriate to incorporate European standards by reference, in this case the European procedure does not produce results that are directly comparable to the DOE test procedure results. AHAM, No. 33 at p.
13
In conducting this test procedure rulemaking, DOE reviewed relevant industry standards, including AHAM
HLD1 and IEC Standard 61121. The

DOE test procedure continues to reference AHAM HLD1. Because adoption of AHAM HLD1 in its entirety would impact the measured energy use of clothes dryers for purposes of determining compliance with DOE standards, DOE did not amend appendix D1 or appendix D2 to adopt AHAM HLD1 in its entirety in this rulemaking. Consistent with its 2020 amendments to the Process Rule at 10 CFR part 430, subpart C, Appendix A, DOE will, however, consider adoption of AHAM HLD1 in its entirety in a subsequent rulemaking prior to any rulemaking to consider whether to amend the energy conservation standards applicable to clothes dryers.
As noted, the 2009 version of AHAM
HLD1 has been certified as ANSI/
AHAM HLD12010. ANSI certification ensures that the standard has been developed through a process that meets ANSIs requirements for openness, balance, consensus, and other due process safeguards.53 The certification of AHAM HLD1 as ANSI/AHAM HLD
12010 does not result in any substantive changes to the industry standard. In this final rule, DOE is updating the reference to AHAM HLD
1 in appendix D1 and appendix D2 to the 2010 version of ANSI/AHAM HLD
1. This update to the most recent version of AHAM HLD1 does not result in any changes to the clothes dryer test procedures at appendix D1 and appendix D2.
I. Effective and Compliance Dates The effective date for the adopted test procedure amendments will be 30 days after publication of this final rule in the Federal Register. EPCA prescribes that all representations of energy efficiency and energy use, including those made on marketing materials and product labels, must be made in accordance with an amended test procedure, beginning 180 days after publication of the final rule in the Federal Register. 42 U.S.C.
6293c2 EPCA allows individual manufacturers to petition DOE for an extension of the 180-day period if the manufacturer may experience undue hardship in meeting the deadline. 42
U.S.C. 6293c3 To receive such an extension, petitions must be filed with DOE no later than 60 days before the end of the 180-day period and must detail how the manufacturer will experience undue hardship. Id. To the extent the modified test procedure adopted in this final rule is required 53 More information on ANSIs standards process may be found at: www.ansi.org/standards_
