25、ommon CSA and UL standard for hand-held motor-operated electric tools. It is the second edition of CAN/CSA-C22.2 No. 60745-2-8 and the second edition of UL 60745-2-8. This standard is an adoption of IEC 60745-2-8, second edition. The rst edition of this standard was designated CAN/CSA-C22.2 No. 745-
26、2-8/UL 745-2-8. This Standard CAN/CSA-C22.2 No. 60745-2-8/UL 60745-2-8, second edition, supersedes: a) the rst edition CAN/CSA-C22.2 No. 745-2-8/UL 745-2-8 published in 1995; and b) CAN/CSA-C22.2 No. 745-4-8/UL 745-4-8, (requirements for battery tools and battery packs are now incorporated into the
27、requirements of CAN/CSA-C22.2 No. 60745-2-8, second edition, and UL 60745-2-8, second edition). The standard number has been aligned to correspond with the equivalent IEC 60745-2-8 standard. This common standard was prepared by the Canadian Standards Association (CSA) and Underwriters Laboratories I
28、nc. (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 Requirements for Electrical Safety, and has been formally approved by the CSA
29、 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 Standard. Note: Although the intended primary application of this standard is st
30、ated 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 recently adopted revisions, all of which are itemized on the transmittal notice
31、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 adopts the IEC text. This standard is published as an equivalent standard for C
32、SA 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 regulations as well as those recognized as being in accordance with NAFTA Article 905, for example because of
33、fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. MARCH 26, 2004 CAN/CSA-C22.2 NO. 60745-2-8-04 UL 60745-2-8 5UL COPYRIGHT

35、 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 development organizations to more accurately reect the intent. CSA effective date The effective date f
36、or CSA International will be announced through CSA Informs or a CSA certication notice. UL effective date The effective date for UL 60745-2-8, second edition, is October 31, 2012. Between the present and October 31, 2012, new product submittals to UL must be evaluated under all requirements in this
37、Standard or, if requested in writing, evaluated under presently effective requirements only. The presently effective requirements are contained in the rst edition of UL 745-2-8. As of October 31, 2012, all products Listed or Recognized by UL shall comply with the requirements in this standard. A UL

39、TROTECHNICAL COMMISSION HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY PART 2-8: PARTICULAR REQUIREMENTS FOR SHEARS AND NIBBLERS FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Na
40、tional 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, Technical Specications, Technical Reports, Publicl
41、y 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 work. International, governmental and nongovernmental
42、 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) The formal decisions or agreements of IEC on techn
43、ical 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 recommendations for international use and are accepted by IE
44、C 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 unifor
45、mity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) I
46、EC 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 liability shall attach to IEC or its directors,
47、 employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out
48、of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to
49、 the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. This part of International Standard IEC 60745-2-8 has been prepared by sub-committee 61F: Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household and similar electrical appliances.
