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withdrawn at the latest by April 2020.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.
