11、al Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising 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

12、fields. To this end and in addition to other activities, IEC publishes International Standards, 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

13、 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. IEC collaborates closely with the International Organization for Standardi

14、zation (ISO) in accordance with conditions determined by agreement between the two organizations. 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 repres

15、entation from all interested IEC 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 accurate, IEC

16、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 regional publica

17、tions. 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 I

18、EC 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, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal inju

19、ry, 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 Normative references c

20、ited 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 responsible for identif

21、ying any or all such patent rights. This part of International Standard IEC 60745 has 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 60745-2-2

22、1 consists of the first edition (2002) documents 61F/483/FDIS and 61F/504/RVD and its amendment 1 (2008) documents 61F/739/FDIS and 61F/759/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

23、1.1. A vertical line in the margin shows where the base publication has been modified by amendment 1. The French version of this standard has not been voted upon.

24、IEC:2002+A1:2008 3 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 electric tools Safety Part 1: General requirements, and its amendments. It was established

25、 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, so as to convert that publication into the IEC standard: Safety requirements for dra

26、in cleaners. 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 system i

27、s 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 types are used: requirements: in roman type; test specifications: in italic type; notes: in smaller

28、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 established on the basis of the fourth edition (2006) of IEC 60745-1, Hand-held motor-operated electric too

29、ls 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 contents of the base publication and its amendments will remain unchanged until the maintenance resul

30、t 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 edition, or amended. SANS 60745-2-21:2010This s tandard may only be used and printed by approved sub
