Standards and Test Procedures 

The Department of Energy (DOE) establishes energy-efficiency standards for certain appliances and equipment, and currently covers more than 70 different products. Authority to undertake this effort was granted by Congress, and DOE follows a four-phase process when reviewing existing and developing new standards. Each product page provides information on recent updates, current standards and test procedures, waivers, exceptions, and exemptions, statutory authority, and historical information.
