DIN EN 12942:2017-02

This European Standard specifies minimum requirements for powered Respiratory Protective devices (RPD) which incorporate a full face mask, half mask or a quarter mask together with gas, particle or combined filter(s) used as respiratory protective devices. It does not cover devices designed for use in circumstances where there is or might be an oxygen deficiency (concentration in oxygen less than a volume fraction of 17%). Escape RPD are not covered by this European Standard. Laboratory tests and practical performance tests are included for the assessment of compliance with the requirements.
