Voluntary Standards Cover the Spectrum: from Solar Energy to Fireplaces

New York, Nov 15, 2007

In an effort to communicate the vital role that standards play in daily life, ANSI Online will publish, on an ongoing basis, a series of snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Solar Energy
As the need for alternative energy resources continues to grow, solar panels are becoming increasingly common sources of heat, light, hot water and electricity for homes and businesses. Solar panels work by converting sunlight into electricity through a photovoltaic cell, a non-mechanical device that is usually made from silicon alloys.

Technical Committee (TC) 82 of the International Electrotechnical Commission (IEC) recently published IEC 60904-9 Ed. 2.0 b:2007, Photovoltaic devices - Part 9: Solar simulator performance requirements. The revised standard defines classifications of solar simulators for use in indoor measurements of photovoltaic devices. The classifications – A, B, and C – are based on specified criteria such as spectral distribution match, irradiance non-uniformity on the test plane, and temporal instability. The main change with respect to the previous edition of IEC 60904-9 consists of a redefinition of the classifications and additional measurement procedures.

The U.S. holds the secretariat for IEC TC 82, which prepares international standards for solar photovoltaic energy systems.

With the weather turning colder, consumers are once again gathering around their fireplaces for heat and holiday cheer. Product safety certification organization Underwriters Laboratories (UL), an American National Standards Institute (ANSI) member and accredited standards developer, recently released a new standard to help protect consumers from unintentional fires.

ANSI/UL 737-2007, Standard for Safety for Fireplace Stoves, covers freestanding fireplace stoves that are attached to a residential chimney. Whether operated open to the room or equipped with doors, the standard addresses fireplace stoves that are fueled by solid wood or coal.

ANSI/UL 737-2007 is intended for fireplace stoves installed in accordance with NFPA 211, Standard for Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances, a family of fireplace standards produced by ANSI member and accredited standards developer the National Fire Protection Association.
