Foreword
The text of document 116/41/FDIS, future edition 5 of IEC 60745-2-5, prepared by TC 116, Safety
of hand-held motor-operated electric tools, was submitted to the IEC-CENELEC parallel vote.
A draft amendment, which covers common modifications towards future IEC 60745-2-5 (116/41/FDIS),
was prepared by CENELEC Technical committee TC 116, Safety of hand-held motor operated electric
tools. It was submitted to the formal vote.
The combined texts were approved by CENELEC as EN 60745-2-5 on 2010-10-01.
This European Standard supersedes EN 60745-2-5:2007 + A11:2009.
Main changes include: in Clause 17, Endurance: introduction of endurance tests in practical use for
the guards of all types of saws; in Clause 19, Mechanical hazards: clarifications and editorial
improvement in respect to the guarding; and in Annex M, Safety of working stands for operation with
hand-held motor-operated electric tools: editorial improvements.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the amendment has to be implemented

at national level by publication of an identical

national standard or by endorsement
(dop) 2011-10-01

– latest date by which the national standards conflicting

with the amendment have to be withdrawn
(dow) 2013-10-01
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 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 Mandate M/396 given to CENELEC by the
European Commission and the European Free Trade Association and covers essential requirements
of EC Directive 2006/42/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 255 is producing standards for non-electric circular saws (EN 792-12).
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.

Part 2-5: Particular requirements for circular 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services 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, 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 60745-2-5 has been prepared by IEC technical committee 116:
Safety of hand-held motor-operated electric tools.
This fifth edition cancels and replaces the fourth edition published in 2006, of which it
constitutes a technical revision.
Main changes include: in Clause 17, Endurance: introduction of endurance tests in practical
use for the guards of all types of saws; in Clause 19, Mechanical hazards: clarifications and
editorial improvement in respect to the guarding; and in Annex M, Safety of working stands for
operation with hand-held motor-operated electric tools: editorial improvements.
