This European Standard specifies minimum requirements for power assisted respiratory protective devices 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 17 % by volume). Also, it does not cover respiratory protective devices designed for escape purposes. Laboratory tests and practical performance tests are included for the assessment of compliance with the requirements.
