Introduction A given respiratory protective device can only be approved when its individual components satisfy the requirements of th
38、e test specification which can be a complete standard or part of a standard, and practical performance tests have been carried out successfully on a complete device where specified in the appropriate standard. If, for any reason a complete device is not tested then simulation of the device can be do
39、ne provided the respiratory characteristics and weight distribution are similar to those of the complete device. 1 Scope 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 wi
40、th 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 design
41、ed tor escape purposes. Laboratory tests and practical performance tests are included for the assessment of compliance with the requirements. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
