The Association of Home Appliance Manufacturers or AHAM represents the manufacturers of household appliances and products/services associated with household appliances sold in the United States. AHAM also develops and maintains technical standards for various appliances to provide uniform, repeatable procedures for measuring specific product characteristics and performance features. AHAM is an ANSI accredited Standards Development Organization, and maintains several standards which are approved by ANSI through the consensus approval process. AHAM standards are also recognized by many regulatory agencies including the United States Environmental Protection Agency and the U.S. Department of Energy. In addition to publishing standards, AHAM also provides regular information and advocacy to members before other standards development organizations such as Underwriters Laboratories, the Canadian Standards Association, ASTM, IEC and ISO. AHAM administers voluntary certification programs to rate appliances developed by members and non-members. Testing is conducted by third-party laboratories and, upon certification, appliances may carry the AHAM seal.
