25、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 standard is based on edition 2 of IEC 607
26、45-2-6. 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
27、the 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 Inst
28、itute (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 curr
29、ent only if it incorporates the most recently 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.
30、 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 al
31、lowed 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
32、propriate. Presentation is word for word except for editorial changes. 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
33、 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 development organizations to more accurately reect the intent. CSA effective date The effective date for CSA International wil
34、l be announced through CSA Informs or a CSA certication notice.

35、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 National Difference in the
36、 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 for Hammers, copyright
37、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 consumers and users of pr
38、oducts. 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 the IEC standard. DC Thes
39、e 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.

43、L ELECTROTECHNICAL COMMISSION HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY PART 2-6: PARTICULAR REQUIREMENTS FOR HAMMERS FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National
44、 Committees). The object of the 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, the IEC publishes International Standards. Their preparation is entrusted to technical comm
45、ittees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organizatio
46、n for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical c
47、ommittee has representation from all interested National Committees. 3) IEC Publications have the form of recommendations 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
48、 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 possible in their national and r
49、egional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liabi
