32、f the Canadian Electrical Code, Part II, see the preface of CSA C22.2 No. 0, General RequirementsCanadian 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 a Subcommittee of the Techni

33、cal Committee on Consumer and Commercial Products under the jurisdiction of the Standards Steering Committee on CE Code, Part II, and was formally 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 inten

34、ded 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 standar

35、dization 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
