27、tioning Devices. It is the second edition ofCSA C22.2 No. 18.5, and the fifth edition of UL 1565. This edition of CSA-C22.2 No. 18.5 supersedes theprevious edition published in 2002. This edition of UL 1565 supersedes the previous edition published in2002.This harmonized Standard was prepared by Und

28、erwriters Laboratories and CSA Group. The efforts andsupport of the members of the Technical Harmonization Committee, which includes end productmanufacturers and material suppliers, are gratefully acknowledged.This Standard is considered suitable for use for conformity assessment within the stated s

29、cope of theStandard.This Standard was reviewed by the Technical Subcommittee on ICCM03-Fittings, Hardware andPositioning Devices, under the jurisdiction of the Technical Committee on Wiring Products, and has beenformally approved by the Technical Committee.This standard has been approved by the Amer

30、ican National Standards Institute (ANSI) as an AmericanNational Standard.Where reference is made to a specific number of samples to be tested, the specified number isconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it is important

31、 to note that it remainsthe responsibility of the users of the standard to judge its suitability for their particular purpose.Level of harmonizationThis Standard is published as an equivalent standard for CSA and UL. An equivalent standard is astandard that is substantially the same in technical con

32、tent except as follows. Technical deviations areallowed for Codes and Governmental Regulations, and those recognized as being in accordance withNAFTA Article 905, for example because of fundamental, climatic, geographical, technological orinfrastructural factors, scientific justification or the leve

33、l of protection that the country considersappropriate. Presentation is word for word except for editorial changes.InterpretationsThe interpretation by the SDO (Standards Development Organization) of an equivalent standard shall bebased on the literal text to determine compliance with the standard in

34、 accordance with the proceduralrules of the SDO. If more than one interpretation of the literal text has been identified, a revision shall beproposed as soon as possible to each of the SDOs to more accurately reflect the intent.CSA Group effective dateThe effective date for CSA Group will be announc

39、ted electrical sleeving,extruded insulating tubing, metallic or nonmetallic raceways or woven flexible nonmetallic tubing (fiberloom) employed as mechanical protection for insulated wires or equipment covered by other standards orrequirements.Note 1: Cable ties and cable tie accessories are covered

40、in the Standard for Cable Ties for Electrical Installations,CAN/CSA-C22.2 No. 62275 or UL 62275.Note 2: Nonmetallic Mechanical Protective Tubing (NMPT) is covered in the Standard for Nonmetallic MechanicalProtective Tubing (NMPT), CSA C22.2 No. 227.3 or UL 1696.1.3 These requirements do not apply to

41、 any mechanical protection or electrical insulation that is providedby these devices.1.4 These requirements do not apply to hardware for the support of conduit, tubing, and cable from abuilding structure, such as hangers, staples, straps, and similar devices for installation in accordance withthe Na

42、tional Electrical Code, NFPA 70, and the Canadian Electrical Code (CE Code) Part I.Note: Hardware for the support of conduit, tubing, and cable from a building structure such as hangers, staples,straps, and similar devices for installation in accordance with the National Electrical Code, NFPA 70, an

43、d theCanadian Electrical Code (CE Code) Part I are covered in the Standard for Hardware for the Support of Conduit,Tubing, and Cable, CSA C22.2 No. 18.4 or UL 2239.1.5 In Canada, the requirements in this standard generally address class of workmanship in accordancewith the Canadian Electrical Code (
