范围1。1本标准适用于变压器和电源，包括拟连接至2级电源的变压器和电源，其为霓虹灯和冷阴极管（放电管）提供电压和镇流器，并拟根据加拿大电气规范使用，第I.1.2部分本标准不适用于（a）用于提供其他形式照明（如荧光灯、高强度放电、电致发光、LED和等离子照明）的变压器或电源（b）用于燃油燃烧器的变压器或电源1。3以SI（公制）单位给出的数值为标准。括号中给出的值仅供参考1。 4除非另有说明，本标准中的所有电压和电流值均为均方根（rms）1.5在CSA标准中，“应”用于表示要求，即用户必须满足的条款，以符合本标准；“应该”用于表示建议或建议但不需要的建议；“可”用于表示一种选择或在标准范围内允许的选择；“can”用来表示可能性或能力。注释随附条款不包括要求或替代要求；随附条款的注释的目的是将解释性或信息性材料与文本分开。 表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）以定义其应用。

Scope1.1This Standard applies to transformers and power supplies, including those intended to be connected to a Class 2 source of supply, that provide the voltage and ballasting for neon and cold-cathode tubing (electric-discharge tubing) and are intended to be used in accordance with the Canadian Electrical Code, Part I.1.2This Standard does not apply to(a) transformers or power supplies intended to supply other forms of lighting such as fluorescent, high-intensity-discharge, electroluminescent, LED, and plasma lighting(b) transformers or power supplies that are intended for use with oil burners1.3The values given in SI (metric) units are the standard. The values given in parentheses are for information only1.4Unless otherwise indicated, all voltage and current values in this Standard are root-mean-square (rms)1.5In 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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. 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. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
