26、Electric Tools Safety Part 2-22: Particular Requirements for Cut-Of f Machines. It is the firs edition of CAN/CSA C22.2 No. 60745-2-22, and the firs edition of UL 60745-2-22. This harmonized standard has been jointly revised on June 19, 2014. For this purpose, CSA Group and UL are issuing revision p
27、ages dated June 19, 2014. This harmonized standard is based on IEC Publication 60745-2-22: First edition, Hand-held motor-operated electric tools Safety Part 2-22: Particular requirements for cut-of f machines issued 03-2011. IEC publication 60745-2-22 is copyrighted by the IEC. This harmonized stan
28、dard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). The ef forts and support of the Binational Working Group for Adoption of IEC tool standards, are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the
29、standard. This standard was reviewed by the CSA Subcommittee on Safety of Hand-Held Motor-Operated Electric Tools, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been fo
30、rmally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards Council of Canada (SCC).

Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one literal
41、interpretation has been identified a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reflec the intent.
