1.1

This 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.

This 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 burners

1.3

The values given in SI (metric) units are the standard. The values given in parentheses are for information only

1.4 

Unless otherwise indicated, all voltage and current values in this Standard are root-mean-square (rms)

1.5

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; "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
