About This Item

This standard applies to pressure reducers for gaseous breathing oxygen systems and for all performance profiles without regard to particular inlet or outlet pressures. Attention is given, however, to construction requirements for reducers with maximum supply pressures to 2250 psig (155 bar) and reduced pressures of 50 to 150 psig (3.4 to 10.5 bar). Recent certification requirements have defined requirements of the oxygen systems more precisely with an effect on the design requirements for oxygen pressure reducers. This update makes the designer aware about these requirements: as the need for Oxygen Hazard Analysis, recommended test methods for oxygen intrinsic hazards verification (pressure shock tests and promoted ignition tests) and requirements for pressure factors (max operating pressure, proof, burst and transient pressures). In addition, this version considers actual references and editorial changes. AS1248B has been reaffirmed to comply with the SAE Five-Year Review policy.
