1、BRITISH STANDARD BS EN 60745-2-13:2007 Hand-held motor-operated electric tools Safety Part 2-13: Particular requirements for chain saws The European Standard EN 60745-2-13:2007 has the status of a British Standard ICS 25.140.20; 65.060.80 ? BS EN 60745-2-13:2007 This British Standard was published u
2、nder the authority of the Standards Policy and Strategy Committee on 31 October 2007 BSI 2007 ISBN 978 0 580 54444 6 National foreword This British Standard is the UK implementation of EN 60745-2-13:2007. It was derived by CENELEC from IEC 60745-2-13:2006. It supersedes BS EN 50144-2-13:2002, which
3、will be withdrawn on 1 March 2010. The CENELEC common modifications have been implemented at the appropriate places in the text and are indicated by tags (e.g. ). The UK participation in its preparation was entrusted by Technical Committee CPL/61, Safety of household and similar electrical appliance
4、s, to Subcommittee CPL/61/6, Portable motor-operated tools. A list of organizations represented on this committee can be obtained on request to its secretary. The UK, as a member of CENELEC, is obliged to publish EN 60745-2-13:2007 as a British Standard. However, attention is drawn to the fact that
5、during the development of this European Standard, the UK voted against its approval as a European Standard. The UK does not support the run down time exceeding 1 second in 19.113. This is a relaxation of the run down time of 1 second that is specified in BS EN 50144-2-13:2002, which is superseded by
6、 this standard. This could lead to less safe machines being placed on the market. In the opinion of the UK committee, 19.113 should be amended and the committee intends to actively pursue an agreement from CENELEC to implement an amendment to the standard. This publication does not purport to includ
7、e all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations.

15、hold and similar electrical appliances, together with the common modifications prepared by the Technical Committee CENELEC TC 61F, Safety of hand-held and transportable motor-operated electric tools, was submitted to the CENELEC Unique Acceptance Procedure and was approved by CENELEC as EN 60745-2-1
16、3 on 2007-03-01. This European Standard supersedes EN 50144-2-13:2002. 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) 2008-03-01 latest date by which the national standards c
17、onflicting with the EN have to be withdrawn (dow) 2010-03-01 This 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
18、 standard; Part 2: Requirements for particular 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. This European Standard has been prepared under a mandate given to CENELEC by the Europea
19、n Commission and the European Free Trade Association and covers essential requirements of EC Directive 98/37/EC (Machinery Directive), amended by Directive 98/79/EC. See Annex ZZ. Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with the essential heal
20、th and safety requirements of the Directive concerned. CEN/TC 144 is producing standards for non-electric chain saws (EN 608). Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this standard. This standard follows the overall requiremen
21、ts of EN ISO 12100-1 and EN ISO 12100-2. This Part 2-13 is to be used in conjunction with EN 60745-1:2006. When this standard states “addition“, “modification“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly. Subclauses, items, tables and figures which are additional to th
22、ose in Part 1 are numbered starting from 101. Subclauses, notes, tables and figures which are additional to those in IEC 60745-2-13:2006 are prefixed “Z”. Annexes ZA and ZZ have been added by CENELEC. NOTE In this standard the following print types are used: - Requirements proper; - Test specificati
