      Preface


      This is the harmonized CSA Group and UL standard for lampholders. It is the seventh edition of CSA C22.2 No. 43, and the fourteenth edition of UL 496. This edition of CSA C22.2 No. 43 supersedes the previous editions published in 2008, 2004, 1984, 1965, 1958, and 1937. This edition of UL 496 supersedes the previous edition published in 2008. This harmonized standard has been jointly revised on March 28, 2022. For this purpose, CSA Group and UL are issuing revision pages dated March 28, 2022.


      This harmonized standard was prepared by a task force comprising members representing CSA Group, Underwriters Laboratories Inc. (UL), NEMA (National Electrical Manufacturers Association), and EFC (Electro-Federation Canada). The efforts and support of the Technical Harmonization Committee for Lampholders of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA) are gratefully acknowledged.


      This standard is considered suitable for use for conformity assessment within the stated scope of the standard.


      This standard was reviewed by the CSA Integrated Committee on Lighting Products, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee.


      This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
