Hand-held motor-operated electric tools - Safety - Part 2-23: Particular requirements for die grinders and small rotary tools

IEC 60745-2-23:2012 applies to die grinders and small rotary tools for mounted accessories not exceeding 55 mm in diameter and mounted sanding accessories not exceeding 80 mm in diameter such as, threaded cones or plugs that are threaded on a mandrel with an unrelieved shoulder flange, mandrel mounted wheels and rotary files with a rated speed not exceeding a peripheral speed of the accessory of 80 m/s at rated capacity. This part 2 is to be used in conjunction with the latest edition of IEC 60745-1 and its amendments. It was established on the basis of the fourth edition (2006) of that standard. This standard does not apply to straight and vertical grinders utilizing flanges for driving an abrasive accessory. Those tools are covered by IEC 60745-2-3. Keywords: Die grinders, rotary tools, grinding, sanding.

Foreword
The text of document 116/111/FDIS, future edition 1 of IEC 60745-2-23, prepared by IEC/TC 116
"Safety of motor-operated electric tools" was submitted to the IEC-CENELEC parallel vote and
approved by CENELEC as EN 60745-2-23:2013.
A draft amendment, which covers common modifications to IEC 60745-2-23 (116/111/FDIS),
was prepared by CLC/TC 116 "Safety of motor-operated electric tools" and approved by
CENELEC.
The following dates are fixed:

(dop) 2013-11-03
• latest date by which the document has
to be implemented at national level by

standards conflicting with the
document have to be withdrawn
This Part 2-23 is to be used in conjunction with EN 60745-1:2009 + A11:2010.
When this standard states "addition", "modification" or "replacement", the relevant text in Part 1 is to
be adapted accordingly.
NOTE 1  When “Part 1” is mentioned in this standard, it refers to EN 60745-1.

This part 2 supplements or modifies the corresponding clauses in EN 60745-1, so as to convert that
publication into the EN standard: Safety requirements for die grinders and small rotary tools.

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, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a
replaced clause or subclause;
– 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 small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the
adjective, the adjective and the associated noun are also in bold.

Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
IEC 60745-2-23:2012 are prefixed “Z”.

This document 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 document follows the overall requirements of EN ISO 12100.
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying
any or all such patent rights.

This document has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association, and supports essential requirements
of EU Directive.
For the relationship with EU Directive see informative Annex ZZ, which is an integral part of
this document.
