Scope: This standard stipulates the purity requirements of compressed air for diving breathing and the oxygen, nitrogen and nitrogen used for preparing diving breathing gas, and the maximum allowable value of the main pollutant components of the ambient gas in saturated diving chambers. This standard also stipulates the detection method for the main pollutant components of the ambient gas in the diving chamber saturated with compressed air, oxygen, nitrogen and helium used for diving breathing. This standard applies to air diving, mixed gas diving and saturation diving, and also applies to the design, manufacture and maintenance of diving systems, diving equipment and diving gear related to diving breathing gases.
