Preface

This is the fifth edition of CSA C22.2 No. 74, Equipment for use with electric discharge lamps, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1996, 1992, 1969, and 1954.

This edition incorporates, in three parts, requirements for fluorescent light ballasts, high-intensity discharge lamp ballasts, and ancillary equipment such as lampholders and starters.

The following sections have changed in this edition:

a) spacings requirements - Clause 4.20.5, Part 1;

b) inrush current - Clause 4.24.4, Part 1;

c) risk of electric shock test - Clause 6.11, Part 1;

d) anti arcing test method - Clause 6.12, Part 1; and

e) harmonics proposal - Clause 4.25, Part 1 and Clause 4.19, Part 2.

This Standard was prepared by Subcommittee on Lighting Products, under the jurisdiction of the Technical Committee on Consumer and Commercial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has formally been approved by the Technical Committee.

Notes:

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization - Code of good practice for standardization as "substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity". It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

b) provide an explanation of circumstances surrounding the actual field condition; and

c) where possible, phrase the request in such a way that a specific "yes" or "no" answer will address the issue.

Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page.

5) This Standard is subject to review within five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee.
