Foreword
The text of the International Standard IEC 60745-2-4:2002, prepared by 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
formal vote and was approved by CENELEC as EN 60745-2-4 on 2003-02-01.
A draft amendment (prAB) was prepared to align Subclause 6.2 with the new Subclause 6.2 in
EN 60745-1. Moreover, vibration values determined with the new 6.2 are complying with the requirements
of the Physical Agents Directive Vibration 2002/44/EC. The text of the draft was submitted to the Unique
Acceptance Procedure and was approved by CENELEC as amendment A11 to EN 60745-2-4:2003 on
2007-02-01.
The text of document 61F/733/FDIS, future amendment 1 to IEC 60745-2-4:2002, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as amendment A1 to EN 60745-2-4:2003
on 2009-04-22.
A further draft amendment (prAC), 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 60745-2-4 on 2009-09-01.
This European Standard supersedes EN 60745-2-4:2003 + A11:2007 + A1:2009.
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) 2010-02-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-05-01
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 supports the essential requirements of
EC Directive 98/37/EC (Machinery Directive), amended by EC Directive 98/79/EC, and of EC Directive
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 Directive concerned.
CEN/TC 255 is producing standards for non-electric sanders and polishers (EN 792-8).
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.
