European foreword
This document (EN 12413:2019) has been prepared by Technical Committee CEN/TC 143 “Machine
tools — Safety”, the secretariat of which is held by SNV.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2020, and conflicting national standards shall be
withdrawn at the latest by April 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12413:2007+A1:2011.
Significant technical differences between EN 12413:2007+A1:2011 and EN 12413:2019 are as follows:
a) Clause 3 “Terms and definitions” has been revised;
b) several modifications throughout the document have been done due to a change of concept
regarding the terms “grinding” and “cutting-off” where the expression “grinding” does not include
“cutting-off” anymore;
c) the abbreviation “RE” for the “Restrictions of use” has been deleted;
d) the type names in Table 6 have been checked and updated (the new edition of ISO 525 that is still
under preparation will also include these revised types);
e) in Table 6, the new Types 17R, 18B, 18P and 19R have been added;
f) 6.2 “Scope of inspection by the manufacturer” has been moved to an informative Annex F
“Recommended scope of the in-process inspection”;
g) in Annex A, requirements for safety symbols (including symbols for personal protective
equipment) have been added;
h) in Table A.2, the following 'restrictions to use' including safety symbols have been added: “Only for
grinding at an angle greater than 10°”. For the 'restriction to use' “Only permitted for totally
enclosed working areas”, a safety symbol has been added;
i) a new Table A.3 with symbols for personal protective equipment and a new safety symbol for "Do
not use a damaged abrasive wheel" has been added;
j) the three point side load test in C.3 has been deleted;
k) Bibliography has been updated.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Introduction
This document has been prepared to provide one means of conforming with essential safety
requirements, e.g. of the General Product Safety Directive and associated EFTA regulations.
This document is addressed to designers, manufacturers and suppliers of the abrasive products
described in the scope. In addition, it helps designers, manufacturers and suppliers of grinding
machines in the selection of abrasive products, in order to reduce the risks and achieve conformity of
the respective machinery with the essential health and safety requirements of the Machinery Directive.
The extent to which hazards are covered is indicated in the scope of this document.
1 Scope
This document is applicable to rotating bonded abrasive products. It specifies requirements and/or
measures for the removal or reduction of hazards resulting from the design and application of the
abrasive products.
This document also contains procedures and tests for verification of compliance with the requirements
as well as safety information for use, which is to be made available to the user by the manufacturer.
This document does not apply to superabrasive products and coated abrasive products.

Note 1 to entry: Types of bonded abrasive products are defined in ISO 525.
3.2 Grinding and cutting-off machines
3.2.1
stationary machine
machine being fixed in position during operation
Note 1 to entry: See for example EN ISO 16089.
Note 2 to entry: Included are fixed swing frame machines and mobile machines clamped firmly in position
during use.
Note 3 to entry: Transportable machines are fixed in position during operation and therefore considered to be
stationary machines.
3.2.2
stationary machine with totally enclosed working area
stationary machine being protected by separating guards in such a way that machining processes are
carried
