Energy Conservation Program: Test Procedures for Residential and Commercial Clothes Washers

This final rule amends the U.S. Department of Energy's ("DOE") test procedures for residential and commercial clothes washers to further specify test conditions, instrument specifications, and test settings; address large clothes container capacities; add product-specific enforcement provisions; delete obsolete provisions; and consolidate all test cloth-related provisions and codify additional test cloth material verification procedures used by industry. This final rule also establishes a new test procedure for residential and commercial clothes washers with additional modifications for certain test conditions, measurement of average cycle time, required test cycles, tested load sizes, semi-automatic clothes washer provisions, new performance metrics, and updated usage factors. The new test procedure will be used for the evaluation and issuance of updated efficiency standards, as well as to determine compliance with the updated standards, should such standards be established.
