European foreword
This document (EN 13274-7:2019) has been prepared by Technical Committee CEN/TC 79 “Respiratory
protection 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 month year of December 2019, and conflicting national
standards shall be withdrawn at the latest by month year of December 2019.
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 13274-7:2008.
The following main technical changes have been made compared to EN 13274-7:2008:
a) reference to EN 13274-5 in storage test (5.5) deleted;
b) test equipment for sodium chloride test and test conditions clarified and summarized in one
subclause;
c) procedure for sodium chloride test revised;
d) calculation of the penetration for sodium chloride revised;
e) test equipment for paraffin oil test and test conditions clarified and summarized in one subclause:
f) procedure for paraffin oil test revised;
g) figures adapted to the changes made in the test procedures, where appropriate.
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

5 Test requirements
5.1 General
Two test aerosols are used for measurement of filter penetration:
a) Sodium Chloride, using the equipment specified in Clause 6;
b) Paraffin Oil, using the equipment specified in Clause 7.
The test aerosol is fed into the test chamber, where the particle filtering device under test is mounted in
a leaktight manner on a suitable adaptor. Aerosol is passed through the device and the aerosol
concentration is measured immediately before and after the particle filtering device by the photometer.
Laboratories should give consideration to the following factors.
— Test chamber should be designed to minimize air velocity variations across the surface of the filter
under test.
— Localized high air velocity (“jets”) can result in arti
