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.
