European foreword
This document (EN 12941:2023) has been prepared by Technical Committee CEN/TC 79 “Respiratory
protective devices”, the secretariat of which is held by DIN.
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 June 2024 and conflicting national standards shall be
withdrawn at the latest by June 2024.
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 12941:1998.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
The following main technical changes have been made compared to EN 12941:1998:
a) Clause 4 Designation was deleted;
b) number of test samples was added to the requirements, where necessary;
c) classification table was amended to cover Hg and NO filter for all classes (TH1, TH2 and TH3);
d) nominal values and tolerances were added;
e) clogging was deleted;
f) warning facilities were amended to cover low energy and low flow warning;
g) visual inspection was changed to inspection and detailed list inserted;
h) test substances and number of test subjects for inward leakage test was changed;
i) requirement for field of vision integrated into the requirements for visor (5.8.3);
j) test for noise level was adapted to the test procedure specified in ISO 16900-14:2020;
k) Annex A was deleted;
l) Annex B was deleted;
m) figures were adapted to the changes made in the test procedures, where appropriate.
