Respiratory protective devices. Breathing gases for diving and hyperbaric applications. Requirements and test methodsBS 8478: 2011 Respiratory protective devices. Breathing gases for diving and hyperbaric applications. Requirements and test methods BS 8478: 2011 specifies requirements and test methods for the composition and purity of breathing gases for use in diving and hyperbaric applications. The toxic and harmful effects of impurities in breathing gases are increased at hyperbaric applications therefore the limiting number of impurities has been reduced
