26、geUL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the common CSA and UL standard for hand-held motor-operated electric tools. It is the second edition of CAN/CSA-C22.2 No. 60745-2-6 and the second edition of UL 745-2-6. This

27、standard is based on edition 2 of IEC 60745-2-6. The rst edition of this standard was designated CAN/CSA-C22.2 No. 745-2-6/UL 745-2-6. This Standard CAN/CSA-C22.2 No. 745-2-6/UL 745-2-6, second edition, supersedes: a) the rst edition CAN/CSA-C22.2 No. 745-2-6/UL 745-2-6 published in 1995; and b) CAN

28、/CSA-C22.2 No. 745-4-6/UL 745-4-6, (requirements for battery tools and battery packs are now incorporated into the requirements of CAN/CSA-C22.2 No. 60745-2-6, second edition, and UL 60745-2-6, second edition). The standard number has been aligned to correspond with the equivalent IEC 60745-2-6 stan

29、dard. This common standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories Inc. (UL). This standard was reviewed by the CSA Subcommittee on Portable Electric Tools, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and th

30、e CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards Council of Canada and has been approved by the American National Standards Instit

31、ute (ANSI) as an American National Standard. 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. A UL standard is curren

Where reference is made to a specic number of samples to be tested, the specied number shall be considered a minimum quantity. L

33、evel 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 allo

36、t 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 interpretation has been identied, a revision is to be proposed as s

37、oon as possible to each of the standards development organizations to more accurately reect the intent. CSA effective date The effective date for CSA International will be announced through CSA Informs or a CSA certication notice. UL effective date The effective date for UL 60745-2-6, second edition

38、, is October 31, 2012. Between the present and October 31, 2012, new product submittals to UL must be evaluated under all requirements in this Standard or, if requested in writing, evaluated under presently effective requirements only. The presently effective requirements are contained in the rst ed

39、ition of UL 745-2-6. As of October 31, 2012, all products Listed or Recognized by UL shall comply with the requirements in this standard. A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard. GENERAL The previous version of CAN CSA C2

40、2.2 No. 60745-2-6-04/UL 60745-2-6 included a national difference to IEC Clause 8.12.1. The national difference was deleted in this version of CAN CSA C22.2 No. 60745-2-6-04/UL 60745-2-6. There are ve types of National Differences as noted below. The difference type is noted on the rst line of the Na

41、tional Difference in the standard. The standard may not include all types of these National Differences. National Differences from the text of International Electrotechnical Commission (IEC) Publication IEC 60745-2-6, Hand-Held Motor-Operated Electrical Tools Safety Part 2-3: Particular Requirements

42、 for Hammers, copyright 2006-03, are indicated by the following notation: DR These are National Differences based on the national regulatory requirements. D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for c

43、onsumers and users of products. D2 These are national differences from IEC requirements based on existing safety practices. These requirements reect national safety practices, where empirical substantiation (for the IEC or national requirement) is not available or the text has not been included in t

44、he IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard.
