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with the amendment have to be withdrawn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.
