Minimum Standard for Gaseous Oxygen Pressure Reducers
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).
Rationale: Recent certification requirements have defined requirements to the oxygen systems more precisely with an effect on the design requirements for oxygen pressure reducers
AS1248 is updated in order to make the designer aware about these requirements:
- Oxygen Hazard Analysis need
- recommended test methods for oxygen intrinsic hazards verification (pressure shock tests and promoted ignition tests) and
- Adding a requirement for pressure factors (max operating pressure, proof, burst and transient pressures)
In addition the standard will be updated for actual references and editorial changes.
