This European Standard was approved by CENELEC on 2011-01-10. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia,

Foreword
The text of the International Standard IEC 61029-2-4:1993 + A1:2001, prepared by
IEC TC 116, Safety of hand-held motor-operated electric tools, together with the common
modifications prepared by the Technical Committee CENELEC TC 116, Safety of motor-
operated electric tools, was submitted to the formal vote and was approved by CENELEC as
EN 61029-2-4 on 2011-01-10.
This document supersedes EN 61029-2-4:2003 + corrigendum April 2003 + A1:2003.
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) 2012-01-10
– latest date by which the national standards conflicting
with the EN have to be withdrawn
(dow) 2014-01-10
In this document, the common modifications to the International Standard are indicated by a
vertical line in the left margin of the text.
This European Standard is divided into two parts:
Part 1 General requirements which are common to most transportable 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 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 the Machinery 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.
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 developments
can be taken into account.
Warning: Other requirements and other EC Directives can be applicable to the products
falling within the scope of this standard.
Part 2-4 is to be used in conjunction with EN 61029-1:2009.
Part 2-4 supplements or modifies the corresponding clauses of EN 61029-1, so as to convert it
into the European Standard: Safety requirements for transportable bench grinders.
– 3 – EN 61029-2-4:2011
Where a particular subclause of Part 1 is not mentioned in this Part 2-4, that subclause applies
as far as is reasonable. Where this Part 2-4 states "addition", "modification" or "replacement",
the relevant text of Part 1 is to be adapted accordingly.
Subclauses, tables and figures which are additional to those in Part 1 are numbered starting
from 101. Subclauses, tables and figures which are additional to those in IEC 61029-2-4 are
prefixed "Z".
NOTE In this European Standard the following print types are used:
- Requirements proper;
- Test specifications;
- Explanatory matter.

1 Scope
This clause of Part 1 is applicable except as follows:
1.1 Addition:
This standard applies to transportable bench grinders (see Figure 101) and combined bench
grinders (see Figure 107) with a wheel diameter and brush diameter not exceeding 200 mm, a
thickness not exceeding 30 mm and a peripheral speed not exceeding 50 m/s, as defined in
