Standard Focuses on Safety of Incandescent Light Bulbs
In an effort to ensure the safe operation of incandescent light bulbs or lamps, the National Electrical Manufacturers Association (NEMA) recently published a revised American national standard (ANS) focused on safety specifications.
Issued on behalf of the American National Standard Lighting Group (ANSLG), parts one and two of ANSI_ANSLG C78.60432-2007, "American National Standard for Electric Lamps -- Incandescent Lamps -- Safety Specifications," have been revised and re-designated to conform to IEC Guide 21-2005, which provides methods for the adoption of international standards as regional or national standards.
Part one of the ANS covers tungsten filament light bulbs, while part two addresses tungsten halogen bulbs for general and home use. The revisions made to both parts concern some international terms and requirements that differ from those commonly used in the United States.
