Scope

This European Standard specifies minimum requirements for fresh air hose breathing apparatus for use with a full face mask, a half mask or a mouthpiece assembly as a respiratory protective device. Two classes of apparatus are covered, the differentiation resulting from mechanical performance and not respiratory protection. Escape and diving apparatus and that used in abrasive blasting operations are not covered by this standard. Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
