25、ER 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. 60745-2-2 and the second edition of UL 60745-2-2. This standard is based on IEC 60745-2-2, second editi

26、on. The rst edition of this standard was designated CAN/CSA-C22.2 No. 745-2-2/UL 745-2-2. This Standard CAN/CSA-C22.2 No. 60745-2-2/UL 60745-2-2, second edition, supersedes: a) the rst edition CAN/CSA-C22.2 No. 745-2-2/UL 745-2-2 published in 1995; and b) CAN/CSA-C22.2 No. 745-4-2/UL 745-4-2, (requi

27、rements for battery tools and battery packs are now incorporated into the requirements of CAN/CSA-C22.2 No. 60745-2-2, second edition, and UL 60745-2-2, second edition). The standard number has been aligned to correspond with the equivalent IEC 60745-2-2 standard. This common standard was prepared b

28、y 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 the CSA Strategic Steering Committee on Req

29、uirements 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 Institute (ANSI) as an American National Standa

30、rd. 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 current only if it incorporates the most recent

31、ly adopted revisions, all of which are itemized on the transmittal notice that accompanies the latest set of revised requirements. Where reference is made to a specic number of samples to be tested, the specied number shall be considered a minimum quantity. Level of harmonization This standard adopt

32、s 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 allowed for codes and governmental regulation

33、s 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 appropriate.

35、t 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 soon as possible to each of the standards de

UL effective date UL 60745-2-2, second edition, was effective on October 31, 2012. A UL effective date is one es

General The previous version of CAN CSA C22.2 No. 60745-2-2-04/UL 60745-2-2 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

38、-2-04/UL 60745-2-2. Annex 2.DVL was originally provided as supplemental information and was considered editorial, Type DE. The annex is now considered no longer necessary, and has been deleted. There are ve types of National Differences as noted below. The difference type is noted on the rst line of

39、 the National Difference in the standard. The standard may not include all types of these National Differences. National Differences from the text of the International Electrotechnical Commission (IEC) publication 60745-2-2 (Hand-Held Motor-Operated Electric Tools Safety Part 2-2: Particular Require

40、ments for Screwdrivers and Impact Wrenches) 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 s

41、afety for consumers 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 in

42、cluded in the 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.

44、 PERMISSION FROM UL INTERNATIONAL ELECTROTECHNICAL COMMISSION HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY PART 2-2: PARTICULAR REQUIREMENTS FOR SCREWDRIVERS AND IMPACT WRENCHES FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisi

45、ng all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards,

46、 Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory wo

47、rk. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2)

48、 The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommend

49、ations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possibl
