13、l vote. A draft amendment, prepared by the Technical Committee CENELEC TC 61F, Safety of hand-held and transportable motor-operated electric tools, was submitted to the formal vote. The combined texts were approved by CENELEC as EN 60745-1 on 2006-06-01. Two draft amendments (prAB and prAC), prepare
14、d by the Technical Committee CENELEC TC 61F (transformed into CENELEC TC 116, Safety of hand-held motor-operated electric tools), were submitted to the Unique Acceptance Procedure. The text of EN 60745-1:2006 together with that of the draft amendments prAB and prAC were approved by CENELEC as a new
15、edition of EN 60745-1 on 2009-03-01. This European Standard supersedes EN 60745-1:2006. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2009-12-29 latest date by which the nat
16、ional standards conflicting with the EN have to be withdrawn (dow) - This European Standard has been prepared under a mandate given to CEN and CENELEC by the European Commission and the European Free Trade Association and supports the essential health and safety requirements of the Machinery Directi
17、ve 2006/42/EC. This European Standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric motor operated tools (for the purpose of this standard referred to simply as tools) which could come within the scope of this standard; Part 2: Requirements for p
18、articular types of tools which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these specific tools. Compliance with the relevant clauses of Part 1 together with a relevant Part 2 of this standard provides one means of conform
19、ing with the essential health and safety requirements of the Directive concerned. A relevant Part 2 is one in which the type of the tool or an accessory which is to be used with the tool is within the scope of that Part 2. When a relevant Part 2 does not exist, Part 1 can help to establish the requi
20、rements for the tool, but will not by itself provide a means of conforming to the relevant essential health and safety requirements of the Machinery Directive. Other standards referred to in this European Standard are also listed in Annex ZA, which gives the valid edition of those documents at the t
21、ime of issue of this EN. 2 BS EN 60745-1:2009+A11:2010EN 60745-1:2009+A11:2010 (E)CEN Technical Committees have produced a range of standards dealing with a similar range of non-electrically powered tools. Where necessary, normative references are made to these standards in the relevant Part 2. This
22、 European Standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. Subclauses, tables and figures which are additional to those in IEC 60745-1 are prefixed “Z”. NOTE 1 In this standard the following print types are used: - requirements proper; in roman type - test specificatio
23、ns: in italic type; - explanatory matter: in smaller roman type. NOTE 2 In Annexes B, K, L and M, subclauses which are additional to those in the main body of the text are numbered starting from 201. The contents of the corrigendum of December 2009 have been included in this copy. 3 Foreword to amen

41、ual countries may wish to consider the application of this Part 1 of IEC 60745, so far as is reasonable, to tools not mentioned in an individual part 2 and to tools designed on new principles. If the functions of a tool are covered by the different parts 2 of IEC 60745, the relevant part 2 is applie
42、d to each function separately, so far as is reasonable. If applicable, the influence of one function on the other is taken into account. A product employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested accordi
43、ng to the intention of the requirements and, if found to be substantially equivalent, may be judged to comply with the standard. Standards dealing with non-safety aspects of hand-held tools are: IEC standards published by TC 59 on methods of measuring performance; CISPR 11 and 14 on radio interferen
44、ce suppression; IEC 61000-3-2 and IEC 61000-3-3 on electromagnetic compatibility. 8 BS EN 60745-1:2009+A11:2010EN 60745-1:2009+A11:2010 (E)HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS SAFETY Part 1: General requirements 1 Scope This part of IEC 60745 deals with the safety of hand-held motor-operated or m
45、agnetically driven electric tools, the rated voltage of the tools being not more than 250 V for single-phase a.c. or d.c. tools, and 440 V for three-phase a.c. tools. So far as is practicable, this standard deals with the common hazards presented by hand-held tools which are encountered by all perso
46、ns in the normal use and reasonably foreseeable misuse of the tools. Tools with an electric heating element are within the scope of this standard. They should also comply with relevant parts of IEC 60335. Requirements for motors not isolated from the supply, and having basic insulation not designed
47、for the rated voltage of the tools, are given in Annex B. Requirements for rechargeable battery-powered motor-operated or magnetically driven tools and the battery packs for such tools are given in Annex K. Those for such tools that are also operated and/or charged directly from the mains or a non-i
48、solated source are given in Annex L. Hand-held electric tools, hereinafter referred to as tools, which can be mounted on a support or working stand for use as fixed tools without any alteration of the tool itself, are within the scope of this standard. Requirements for such supports or working stand
49、s are given in Annex M. This standard does not apply to: hand-held tools intended to be used in the presence of explosive atmosphere (dust, vapour or gas); hand-held tools used for preparing and processing food; hand-held tools for medical purposes (IEC 60601); heating tools which are covered by IEC 60335-2-45; For hand-held tools intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary. For hand-held tools
