Federal Register / Vol. 86, No. 167 / Wednesday, September 1, 2021 / Proposed Rules 15 DOE requests comment on its proposal to require that each test cycle use a bone-dry test load in the proposed new Appendix J. DOE requests comment on whether test laboratories start test cycles with the test load at bone-dry or at up to 104 percent of the bone-dry weight. DOE further requests feedback on its assessment that this change would not affect test burden.
16 DOE requests comment on its proposal to add cycle time measurements and to calculate average cycle time using the weighted-average method in the proposed new Appendix J. DOE also requests comment on its assertion that adding cycle time measurements and a calculation of a weighted-average cycle time would not increase testing costs or overall test burden.
17 DOE requests comment on its tentative determination to maintain the current capacity measurement method.
18 DOE requests comment on the proposed criteria for determining whether test data are to be discarded.
Specifically, DOE requests comment on the proposal that test data are discarded if a washing machine either signals to the user by means of a visual or audio alert that an out-of-balance condition has occurred or terminates prematurely.
DOE requests comment on whether additional or alternate criteria would provide objective and observable indication during a single test that test data are to be discarded.
19 DOE requests comment on its proposal for testing semi-automatic clothes washers in the proposed new Appendix J that would require testing only the wash/rinse temperature combinations that do not require a wash temperature change between the wash and rinse portions of the cycle i.e., Hot/
Hot, Warm/Warm, and Cold/Cold.
20 DOE requests feedback on its proposal to test semi-automatic clothes washers using TUF values of 0.14 for Hot, 0.49 for Warm, and 0.37 for Cold.
21 DOE further requests comment on whether the temperature selections and TUFs that DOE has proposed for semiautomatic clothes washers would be representative of consumer use; and if not, which temperature selections and TUF values would better reflect consumer use.
22 DOE requests comment on whether to include explicit instructions for how to test semi-automatic clothes washers in Appendix J2, and if so, whether DOE should implement the same procedures being proposed for the proposed new Appendix J.
23 DOE requests feedback on how manufacturers of semi-automatic clothes

washers are currently testing their products using Appendix J2.
24 DOE requests comment on its proposal to require semi-automatic clothes washers to test only the Cold cycle, and to determine the representative values for the Warm and Hot cycles formulaically, for the proposed new Appendix J.
25 DOE requests comment on the test burden associated with determining the apportionment between wash water use and rinse water use on semiautomatic clothes washers.
26 DOE requests comment on maintaining the current requirement to use the manufacturer default settings for optional cycle modifiers.
27 DOE requests comment on its proposed amendment to Appendix J2
and the proposed new Appendix J to specify that network settings on clothes washers with network capabilities must be disabled during testing if such settings can be disabled by the end-user, and the products user manual provides instructions on how to do so.
28 DOE requests feedback on its characterization of connected clothes washers currently on the market.
Specifically, DOE requests input on the types of features or functionality enabled by connected clothes washers that exist on the market or that are under development.
29 DOE requests data on the percentage of users purchasing connected clothes washers, and, for those users, the percentage of the time when the connected functionality of the clothes washer is used.
30 DOE requests data on the amount of additional or reduced energy use of connected clothes washers.
31 DOE requests data on the pattern of additional or reduced energy use of connected clothes washers; for example, whether it is constant, periodic, or triggered by the user.
32 DOE requests information on any existing testing protocols that account for connected features of clothes washers, as well as any testing protocols that may be under development within the industry.
33 DOE requests comment on its proposal to replace the capacity term with weighted-average load size in the energy efficiency metrics and the water efficiency metric in the proposed new Appendix J.
34 DOE requests comment on its proposed names for the proposed new efficiency metrics: energy efficiency ratio EER, active-mode energy efficiency ratio AEER, and water efficiency ratio WER.
35 DOE requests comment on its proposal to invert the water efficiency

metric and calculate the newly defined WER metric as the quotient of the weighted-average load size divided by the total weighted per-cycle water consumption for all wash cycles.
36 DOE requests data on the annual amount of laundry washed by consumers, and whether the annual amount of laundry washed by consumers is correlated with clothes washer capacity.
37 DOE requests comment on its proposed updated representation and sampling requirements for RCWs and CCWs.
38 DOE requests comment on its proposal to update the number of annual wash cycles to 234 in the proposed new Appendix J and 10 CFR
430.23j1i and j3i.
39 DOE requests comment on maintaining the assumed final moisture content of 4 percent in the drying energy equation, or whether it should update the assumed final moisture content to 2 percent to align with DOEs Appendix D2 clothes dryer test procedure.
40 DOE requests comment on maintaining the current DEF value of 0.5 kWh/lb.
41 DOE requests comment on maintaining the current DUF value of 0.91.
42 DOE requests comment on its proposal to update the number of hours spent in low-power mode from a fixed 8,465 total hours to a formula based on measured cycle time and an assumed number of annual cycles.
43 DOE requests comment on maintaining the current TUF values.
44 DOE requests comment on its proposal to update the LUFs for the small and large load sizes to be equal to 0.5, consistent with the proposed load size definitions in the proposed new Appendix J.
45 DOE requests comment on maintaining the current water heater efficiency assumptions.
46 DOE requests comment on its proposal to specify the use of hoses not to exceed 72 inches in length in the proposed new Appendix J. DOE also requests comment on the length of inlet hose typically used for testing.
47 DOE requests comment on whether it should amend the test procedure to accommodate potential future clothes washer models for which the maximum load size required by the test procedure conflicts with the maximum load size intended or able to be washed with the cycle required for testing. If so, DOE seeks additional comment on the approaches it has considered, or on any other approaches
