Respiratory protective devices - Particle filters - Requirements, testing, marking
This document specifies particle filters for use as replaceable components in unassisted respiratory protective devices with the exception of escape devices and filtering facepieces.
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.

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.

6 Requirements
6.1 General
All test samples specified in the related test clauses shall meet the relevant requirements.
Where it is required in a specific clause the manufacturer shall declare that a risk assessment, e.g. a
Failure Modes and Effect Analysis (FMEA) has been conducted.
NOTE Further information is given in EN 60812 [1].
6.2 Values and tolerances
Temperature limits, values which describe test conditions and that are not stated as maxima or minima
shall be subject to a tolerance of ± 5 %. Unless otherwise specified, the ambient conditions for testing
shall be between 16 °C and 32 °C and (50 ± 30) % relative humidity.
Any temperature limits specified shall be subject to an accuracy of ± 1 °C.
6.3 Connection
The connection between filter(s) and respiratory interface with which it is intended to be used shall be
robust and leaktight.
The manufacturer shall supply a declaration that this was addressed by a risk assessment, e.g. a FMEA.
Threads conforming to EN 148-2 or EN 148-3 shall not be used.
The connection between filter and facepiece may be achieved by a special connector or by a screw
thread including a thread conforming to EN 148-1:2018.
If the filter is designated to be used on a twin or multiple filter facepiece or has any other thread, it shall
not be possible to connect it to a thread conforming to EN 148-1:2018.
The filter shall be readily replaceable without use of special tools and shall be designed or marked to
prevent incorrect assembly.
Check in accordance with 7.3.
