## Abstract

The U.S. Department of Energy (DOE) establishes new test procedures for residential clothes washers under the Energy Policy and Conservation Act. The new test procedures include provisions for measuring standby mode and off mode energy consumption, and update the provisions for measuring active mode energy and water consumption. This final rule also amends the certification, compliance, and enforcement requirements for residential clothes washers, amends provisions for calculating the estimated annual operating cost for clothes washers, eliminates an obsolete clothes washer test procedure, and amends certain provisions in the currently applicable test procedure.
