CAN/CSA-E922-98 (R2017)

This National Standard of Canada is based on International Standard IEC 922:1989, Including A1-1990 and A2-1992. 1. Scope This standard specifies safety requirements for ballasts for discharge lamps such as high-pressure mercury vapour, low- pressure sodium vapour, high-pressure sodium vapour and metal halide lamps. Section One specifies general requirements and Section Two specifies thermal and mechanical requirements. The standard covers inductive-type ballasts for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz associated with discharge lamps, having rated wattages, dimensions and characteristics as specified in the relevant IEC lamp standards according to IEC Publications 188, 192 and 662. Tests in this standard are type tests. Requirements for testing individual ballasts during production are not included. Notes (1) For certain types of discharge lamp an ignitor is required. (2) Ballasts for tubular fluorescent discharge lamps are covered by IEC Publication 920. This Standard can also apply to inductive-type ballasts associated with discharge lamps specified in the applicable ANSI Standard. This Standard applies to the safety of such equipment designed to be installed on branch circuits not exceeding 750 V and used in accordance with the rules of the Canadian Electrical Code, Part I. Note: Manufacturers designing products for use in Canada may find a helpful summary of the equipment-related requirements of the Canadian Electrical Code, Part I, in CSA Publication SPE-2000. Canadian Deviations are included in this Standard.
