NEMA Publishes Standard on Gauges for Electric Lamp Bases, Lampholders - NEMA ANSI C81.63

December 18, 2006 // Published as a news service by IHS

The 2006 edition of NEMA ANSI_ANSLG C81.63 includes:

• A reference to all International Electrotechnical Commission (IEC) gauge standard sheets adopted as American National Standards Institute (ANSI) standards.
• Standard sheets for a small number of gauges, used mainly in North America, that are not harmonized with IEC.
• U.S. deviations to the IEC standard sheets, which have been adopted as Nationally Acknowledged International Standards that are published in IEC 60061-3.
• Information on first- versus third-angle projection and related standards.

Because this standard is under continuous accreditation maintenance, the following are the changes of record in the 2006 NEMA ANSI_ANSLG C81.63:

• SX4s/4 Flanged CAPS: ANSI standard sheet 1-850-1 is superseded with IEC standard sheet 7004-97-2 - Submidget flanged base for subminiature lamps.
• PGJ19 CAPS for the H8B, H9B and H11B Lamps: Adopted IEC standard sheet 7004-146-1.
• W(X)(Y)3x16q BASE: IEC standard sheet 7004-106-3 supersedes IEC standard sheet 7004-106-2 - Red Double Filament Lamps Base.
• GX8.5 BASE: U.S. adopted IEC standard sheet 7004-143-1.
• GX10 BASE: U.S. adopted IEC standard sheet 7004-144-1.
