23、WORD 1) The International 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 ele
24、ctrical and electronic 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 te
25、chnical committees; any 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 Org
26、anization for Standardization (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 technic
27、al committee has representation 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 Publica
28、tions 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 uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their nation
29、al and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment servi
30、ces and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out 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, serva
31、nts 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 of the publicatio
32、n, 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 the possibility
33、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 60745-2-23 has been prepared IEC technical committee 116: Safety of motor-operated electric tools. The te
34、xt of this standard is based on the following documents: FDIS Report on voting 116/111/FDIS 116/120/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC
35、 Directives, Part 2. 4 60745-2-23 IEC:2012 This part 2 is to be used in conjunction with the latest edition of IEC 60745-1 and its amendments. It was established 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.
36、This part 2 supplements or modifies the corresponding clauses in IEC 60745-1, so as to convert that publication into the IEC standard: Safety requirements for die grinders and small rotary tools. When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as
37、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 is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless
38、notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. NOTE 3 In this standard, the following print types are used: requirements: in roman type; test specifications:
39、 in italic type; notes: in small 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. A list of all parts of the IEC 60745 series, under the general title: Hand-held motor-operated electric too
40、ls Safety, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability 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 b
41、e reconfirmed, withdrawn, replaced by a revised edition, or amended. 60745-2-23 IEC:2012 5 HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY Part 2-23: Particular requirements for die grinders and small rotary tools 1 Scope This clause of Part 1 is applicable, except as follows: Addition: This standard
