This European Standard was approved by CENELEC on 2007-03-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

Foreword
The text of the International Standard IEC 60745-2-13:2006, prepared by SC 61F, Safety of
hand-held motor-operated electric tools, of IEC TC 61, Safety of household 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 60745-2-13 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 conflicting
with the EN have to be withdrawn (dow) 2010-03-01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 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 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 health 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 requirements of EN ISO 12100-1 and EN ISO 12100-2.
This Part 2-13 is to be used in conjunction with EN 60745-1:2006. 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 those in Part 1 are numbered
starting from 101.

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.
