CSA C22.2 NO. 13:13 (R2023)

Preface This is the fourth edition of C22.2 No. 13, Transformers for oil- or gas-burner ignition equipment , 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 1962, 1954, and 1935. Previous editions of this Standard also included requirements for transformers for luminous-tube signs and cold-cathode interior lighting. These products are now covered by CSA C22.2 No. 255, Neon transformers and power supplies. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0, General Requirements-Canadian Electrical Code, Part II. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Subcommittee on Oil or Gas-Burner Ignition Equipment under the jurisdiction of the Technical Committee on Industrial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the 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. Scope 1.1 This Standard applies to transformers for oil- and gas-burner ignition equipment for potentials up to and including 600 V low potential, and 15,000 V open-circuit high-potential, designed to be employed in accordance with the rules of the Canadian Electrical Code, Part I. Note: The terms "low-potential" and "high-potential" are used in this Standard, respectively, for "primary" or "low-voltage", and "secondary" or "high-voltage". 1.2 Transformers covered by this Standard are intended for use as auxiliary equipment for oil- and gas-burning apparatus. 1.3 General requirements applicable to this Standard are specified in the latest edition of CAN/CSA-C22.2 No. 0. 1.4 In CSA standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
