42、andard for Hand-Held Motor-Operated Electric Tools Safety Part 1. It is the third edition of CAN/CSA-C22.2 No. 60745-1 and the fourth edition of UL 60745-1. This standard is based on IEC 60745-1, fourth edition. This standard, CAN/CSA-C22.2 No. 60745-1 third edition and UL 60745-1 fourth edition, su

43、percedes CAN/CSA-C22.2 No. 60745-1, second edition and UL 60745-1, third edition. This common standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories Inc. (UL). This standard is considered suitable for use for conformity assessment within the stated scope of t

44、he 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

45、 formally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada (SCC). This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Where reference is made to a specic number of samples to be

46、 tested, the specied number is to be considered a minimum quantity. Note: Although the intended 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.

47、Level of harmonization This standard adopts the IEC text with national differences. This standard is published as an equivalent standard for CSA and UL. An equivalent standard is a standard that is substantially the same in technical content, except as follows: Technical national differences are all

48、owed for codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers ap

49、propriate. Presentation is word for word except for editorial changes. All national differences from the IEC text are included in the CSA and UL versions of the standard. While the technical content is the same in each organizations version, the format and presentation may differ. Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine complian
