11. Appendix J3 to subpart B of part 430 is revised to read as follows:
Appendix J3 to Subpart B of Part 430
Energy Test Cloth Specifications and Procedures for Determining Correction Coefficients of New Energy Test Cloth Lots
khammond on DSKJM1Z7X2PROD with PROPOSALS3

Note: DOE maintains an historical record of the standard extractor test data and final correction curve coefficients for each approved lot of energy test cloth. These can be accessed through DOEs web page for standards and test procedures for residential clothes washers at DOEs Building Technologies Office Appliance and Equipment Standards website.
1. Objective This appendix includes the following: 1
Specifications for the energy test cloth to be used for testing clothes washers; 2
procedures for verifying that new lots of energy test cloth meet the defined material specifications; and 3 procedures for developing a set of correction coefficients that correlate the measured remaining moisture content RMC values of each new test cloth lot with a set of standard RMC
values established as an historical reference point. These correction coefficients are applied to the RMC measurements performed

during testing according to appendix J or appendix J2 to this subpart, ensuring that the final corrected RMC measurement for a clothes washer remains independent of the test cloth lot used for testing.
2. Definitions AHAM means the Association of Home Appliance Manufacturers.
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.
Lot means a quantity of cloth that has been manufactured with the same batches of cotton and polyester during one continuous process.
Roll means a subset of a lot.
3. Energy Test Cloth Specifications The energy test cloths and energy stuffer cloths must meet the following specifications:
3.1 The test cloth material should come from a roll of material with a width of approximately 63 inches and approximately 500 yards per roll. However, other sizes may be used if the test cloth material meets the specifications listed in sections 3.2 through 3.6 of this appendix.
