The breathable air shall meet the following standards of purity. If not specified otherwise the
contaminants shall be kept to a minimum, but in any event shall not exceed the permissible
exposure level.
The mineral oil content shall be such that the air is without odor of oil.
NOTE: The odor threshold is in the region of 0.3mg/m³.
Compressed breathing air shall have a dew point sufficiently low to prevent condensation
and freezing. Where the apparatus is used and stored at a known temperature the pressure
dew point shall be at least 5 °C below the likely lowest temperature. Where national or state
regulations exist, they shall be observed.
Where the conditions of usage and storage of any compressed air supply is not known the
pressure dew point shall not exceed −11 °C.
