Failure Modes and Effect Analysis (FMEA) has been conducted.
NOTE Further information is given in EN 60812 [1].
5.2 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.

Where respirators are designed to use more than one filter, through which the flow is proportioned, all
relevant requirements specified in this document are to be met by the complete set of filters.
If, however, it is intended that a single filter of a twin or multiple filter device may be used alone, then
the requirements of the full flow rate for the tests, as stated in this document, shall be met.

commercially available package.
5.11 Inhalation resistance
The resistance imposed by filter(s) to the flow of air shall be as low as possible and in no case exceed
the values shown in Table 1. For multi type gas filters with mixed classes and/or types, the value
