EN 60745-2-13:2009 - 2 - Foreword The text of the International Standard IEC 60745-2-13:2006, prepared by IEC SC 61F (transformed into IEC TC 116, Safety of hand-held motor-operated electric tools), together with the common modifications prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116), was submitted to the CENELEC Unique Acceptance Procedure and was approved by CENELEC as EN 60745-2-13 on 2007-03-01. A draft amendment (prAB), extending Annex ZZ to include the new MD 2006/42/EC, was submitted to the formal vote. The combined texts were approved by CENELEC as a new edition of EN 60745-2-13 on 2009-06-01. This European Standard supersedes EN 60745-2-13:2007. 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

2009-12-29 – latest date by which the national standards conflicting with the EN have to be withdrawn

2009-12-29 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 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 European Commission and the European Free Trade Association and covers essential requirements of EC Directives 98/37/EC (Machinery Directive), amended by Directive 98/79/EC, and 2006/42/EC. See Annexes ZZA and ZZB. Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with the essential health and safety requirements of the Directives 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 requirements of EN ISO 12100-1 and EN ISO 12100-2. This Part 2-13 is to be used in conjunction with EN 60745-1:2009. 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 those in Part 1 are numbered starting from 101. SIST EN 60745-2-13:2009

HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS – SAFETY–
Part 2-13: Particular requirements for chain saws

FOREWORD 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 electrical 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 technical 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 Organization 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 technical 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 Publications 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 national 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 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 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 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 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 identifying any or all such patent rights. International Standard IEC 60745-2-13 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 second edition cancels and replaces the first edition published in 1989. This edition constitutes a technical revision. Main changes include Clause 8: Markings and instructions, introducing detailed safety warnings; Clause 19: Mechanical hazards, with requirements for handles, hand guards, guarding of moving parts, chain catcher, spiked bumper, chain brake, computed kickback angle, guide bar cover, saw chain tension, oiler, balance and run down time; Clause 20: Mechanical strength, with requirements for handles and hand guards; Clause 21: Construction, with requirements for the insulation of knobs and handles.

60745-2-13  IEC:2006 – 9 – The text of this standard is based on the following documents: FDIS Report on voting 61F/625/FDIS 61F/637/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 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 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. 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 chain saws.

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 is used: – subclauses, items, 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 roman type. IEC 60745 consists of the following parts, under the general title Hand-held motor-operated electric tools – Safety: Part 1: General requirements Part 2-1: Particular requirements for drills and impact drills Part 2-2: Particular requirements for screwdrivers and impact wrenches Part 2-3: Particular requirements for grinders, polishers and disk-type sanders Part 2-4: Particular requirements for sanders and polishers other than disk type Part 2-5: Particular requirements for circular saws
