11、5-2-11 IEC:2003+A1:2008 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY Part 2-11: Particular requirements for reciprocating saws (jig and sabre saws) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardiz

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

13、ional 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 IEC National Committee interested in the subject dealt with may participate in

14、 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 Standardization (ISO) in accordance with conditions determined by agreement between the

15、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 representation from all interested IEC National Committees. 3) IEC Publications have

16、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 cannot be held responsible for the way in which they are used or for any misint

17、erpretation 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 nationa

18、l 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

19、 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 injury, property damage or other damage of any nature whatsoever, whether direct or

20、 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 cited in this publication. Use of the referenced publications is indispensable f

21、or 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 identifying any or all such patent rights. International Standard IEC 60745-2-11 has b

22、een prepared by subcommittee 61F: Safety of hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household and similar electrical appliances Main changes include Clause 3: Definitions, introducing detailed definitions for the tools in the scope of this part 2, and Clause

23、 19: Mechanical hazards, introducing requirements for guarding the saw blades. Subclause 2.2.23 has been removed, as the definitions of “normal load” are now generally covered by Part 1. This consolidated version of IEC 60745-2-11 consists of the second edition (2003) documents 61F/466/FDIS and 61F/

24、490/RVD and its amendment 1 (2008) documents 61F/736/FDIS and 61F/756/RVD. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. SANS 60745-2-11:2009 60745-2-11 IEC:2003+A1:2008 3 It bears the edition number 2.1. A vertical lin

25、e 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. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-11 is to be used in conjunction with the third edition of I

26、EC 60745-1: Safety of hand-held motor-operated electric tools Part 1: General requirements. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. With amendment 1, this part 2 is established on the basis of the fourth edition

27、 (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, addition of a new safety warning to Clause 8: Marking and instructions, and clarifications in Annex K. NO

28、TE In this standard, the following print types are used: requirements: in roman type; test specifications: in italic type; notes: in smaller roman type. Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101; additional annexes are lettered AA, BB, etc.
