Foreword
The text of the International Standard IEC 61029-2-10:1998, 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 116, former TC 61F, Safety of hand-held motor-
operated electric tools, was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as EN 61029-2-10 on 2009-12-01.
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 EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-12-01
This European Standard is divided into two parts:
Part 1 General requirements that are common to most transportable electric motor operated tools (for
the purpose of this European Standard referred to simply as tools) which could come within the
scope of this European Standard;
Part 2 Requirements for particular types of tool 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 2006/42/EC. See Annex ZZ.
Compliance with the relevant clauses of Part 1 together with this Part 2 provides one means of
conforming with the specified essential health and safety requirements of the Directive.
The standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2.
For noise and vibration this standard covers the requirements for their measurement, the provision of
information arising from these measurements and the provision of information about the personal
protective equipment required. Specific requirements for the reduction of the risk arising from noise and
vibration through the design of the tool are not given as this reflects the current state of the art.
As with any standard, technical progress will be kept under review so that any development can be taken
into account.
Warning: Other requirements arising from other EC Directives can be applicable to the products falling
within the scope of this standard.

This Part 2-10 is to be used in conjunction with EN 61029-1:2009. This Part 2-10 supplements or modifies
the corresponding clauses of EN 61029-1, so as to convert it into the European Standard: “Safety
requirements for transportable cutting-off grinders”.
Where a particular subclause of Part 1 is not mentioned in this Part 2-10, that subclause applies as far as
reasonable. Where this Part 2-10 states "addition", "modification" or "replacement", the relevant text of
Part 1 is to be adapted accordingly.
Clauses, subclauses, notes, tables and figures which are additional to those in Part 1 are numbered
starting from 101.
Clauses, subclauses, notes, tables and figures which are additional to those in IEC 61029-2-10 are
prefixed “Z”.
NOTE In this European Standard the following print types are used:
- requirements proper: in roman type;
- test specifications: in italic type;
- explanatory matter: in smaller roman type.

upper limit of the rated voltage range
2.101
cutting-off grinder
tool having a rotating abrasive cutting-off wheel fitted on an arm suspended over a table. The table
supports and positions the workpiece, which is fixed in a vice. The arm is pivoted on the support frame or
attached directly to the table. See Figure Z101
2.102
spindle
spindle of the cutting-off grinder which supports and transmits the rotation to the abrasive cutting-off
wheel
2.103
wheel guard
device which partially encloses the abrasive cutting-off wheel in order to protect the user against contact
with the wheel in normal use and against ejection of fragments of the wheel in the protected area in case
of a breakage of the wheel
2.104
rear guard
device behind the abrasive cutting-off wheel that prevents the ejection of sparks
2.105
