29、prising 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 fields. To this end and in addition to other activities, IEC publishes International Sta

30、ndards, Technical Specifications, Technical Reports, Publicly Available Specifications (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 pre

31、paratory work. International, governmental and non- governmental 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 orga

32、nizations. 2) 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

33、 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 accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretat

34、ion 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 regional publications. Any divergence between any IEC Publication and the corresponding national or reg

35、ional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out

36、 by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees

37、 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 of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the

38、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 the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held r

39、esponsible for identifying any or all such patent rights. International Standard IEC 60745-2-5 has been prepared by IEC technical committee 116: Safety of hand-held motor-operated electric tools. This fifth edition cancels and replaces the fourth edition published in 2006, of which it constitutes a

40、technical revision. Main changes include: in Clause 17, Endurance: introduction of endurance tests in practical use for the guards of all types of saws; in Clause 19, Mechanical hazards: clarifications and editorial improvement in respect to the guarding; and in Annex M, Safety of working stands for

41、 operation with hand-held motor-operated electric tools: editorial improvements. 60745-2-5 IEC:2010 5 The text of this standard is based on the following documents: FDIS Report on voting 116/41/FDIS 116/52/RVD Full information on the voting for the approval of this standard can be found in the repor

42、t on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-5 is to be used in conjunction with the fourth edition of IEC 60745-1, Hand-held motor-operated electric tools Safety Part 1: General requirements. It was establ

43、ished on the basis of the fourth edition (2006) of that standard. NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60745-1. This part 2 supplements or modifies the corresponding clauses of IEC 60745-1, so as to convert that publication into the IEC standard: Safety requirements f

44、or circular saws. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The following numbering sys

45、tem is used: subclauses, items, tables and figures that are numbered starting from 101 are additional to those in Part 1; additional annexes are lettered AA, BB, etc. NOTE 3 In this standard, the following print types are used: requirements: in roman type; test specifications: in italic type; notes:

46、 in smaller roman type. A list of all parts of the IEC 60745 series, under the general title: Hand-held motor-operated electric tools Safety, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability dateindicated on th

47、e IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 6 60745-2-5 IEC:2010 HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY Part 2-5: Particular requirements

48、 for circular saws 1 Scope This clause of Part 1 is applicable, except as follows: Addition: This standard applies to circular saws, which hereinafter will be referred to as saws. This standard does not apply to saws designed for use with abrasive wheels. NOTE Saws designed for use with abrasive whe
