23、omprising 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 S
24、tandards, 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 p
25、reparatory 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 org
26、anizations. 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 for
27、m 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 misinterpreta
28、tion 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 re
29、gional 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 p
30、ublication. 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 for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indire
31、ct, 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 Normative references cited in this publication. Use of the referenced publications is indispensable for the
32、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 responsible for identifying any or all such patent rights. This part of International Standard IEC 60745 has
33、been prepared by subcommittee 61F: Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household and similar electrical appliances This consolidated version of IEC 60745-2-8 consists of the second edition (2003) documents 61F/465/FDIS and 61F/489/RVD and its a
34、mendment 1 (2008) documents 61F/735/FDIS and 61F/755/RVD. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. It bears the edition number 2.1. A vertical line in the margin shows where the base publication has been modified b
35、y amendment 1. The French version of this standard has not been voted upon. 4 60745-2-8 IEC:2003+A1:2008 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part 2 is to be used in conjunction with the latest edition of IEC 60745-1, Hand-held motor-operated elec
36、tric tools Safety Part 1: General requirements, and its amendments. It was established on the basis of the third edition (2001) 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
37、 so as to convert that publication into the IEC standard: Safety requirements for electric shears and nibblers. 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
38、 the relevant text in Part 1 is to be adapted accordingly. NOTE 2 The following numbering system is used: subclauses, 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
39、types are used: requirements: in roman type; test specifications: in italic type; notes: in smaller roman type. Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated noun are also in bold. With amendment 1, this Part 2 is establi
40、shed on the basis of the fourth edition (2006) of IEC 60745-1, Hand-held motor-operated electric tools Safety Part 1: General requirements. Main changes include editorial modifications to match with the fourth edition of IEC 60745-1 and clarifications in Annex K. The committee has decided that the c
41、ontents of the base publication and its amendments will remain unchanged until the maintenance result date indicated on the 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
42、edition, or amended. 60745-2-8 IEC:2003+A1:2008 5 HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY Part 2-8: Particular requirements for shears and nibblers 1 Scope This clause of Part 1 is applicable except as follows: Addition: This standard applies to shears and nibblers. 2 Normative references Thi
