BS EN 12021:1999 Respiratory protective devices. Compressed air for breathing apparatus

This European Standard specifies requirements for the quality of compressed air supplied for use with the following types of equipment.

a) Respiratory protective devices Ð self-contained open-circuit compressed air breathing apparatus and open-circuit compressed air underwater breathing apparatus (SCUBA).
b) Respiratory protective devices Ð compressed air
line breathing apparatus and compressed airline
breathing apparatus for use under water.
c) Respiratory protective devices for escape Ð
self-contained open-circuit compressed air breathing
apparatus including full face mask or mouthpiece
assembly or hoods.
The standard also applies to synthetic air. Account is
taken of the use of air at normal ambient pressures
and increased pressures. Maximum allowable
concentrations of impurity for compressed air are
quoted as values calculated at normal atmospheric
pressure.
This European Standard does not apply to compressed
air used for medical purposes, for underwater
breathing apparatus specially designed to be used for
diving in water and other fluids when the hydrostatic
pressure exceeds 6 bar absolute or for breathing
apparatus designed for use at high altitudes.
