European foreword
This document (EN 143:2021) 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 August 2021, and conflicting national standards shall
be withdrawn at the latest by August 2021.
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 143:2000, EN 143:2000/A1:2006 and EN 143:2000/AC:2005.
The following main technical changes have been made compared to EN 143:2000:
a) definitions and symbols added;
b) description deleted;
c) nominal values and tolerances changed;
d) use of a risk assessment, e.g. a Failure Modes and Effect Analysis (FMEA) added;
e) twin filters added;
f) clogging deleted;
g) visual inspection changed to inspection and detailed list inserted;
h) filter penetration test changed to refer to EN 13274-7;
i) marking changed to filters in general;
j) all figures adapted to the changes made in the test procedures, where appropriate.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
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,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
1 Scope
This document specifies particle filters for use as replaceable components in unassisted respiratory
protective devices (RPD) with the exception of escape devices and filtering face pieces.
Laboratory tests are included for the assessment of compliance with the requirements.
Some filters complying with this document can also be suitable for use with other types of respiratory
protective devices and/or escape devices. If so, they need to be tested and marked according to the
appropriate European Standard.
This document does not cover requirements concerning respiratory hygiene. Requirements for
decrease of the microbiological hazards caused by the growth of bacteria and viruses on the filtration
material are not determined.
