Product Code:SAE AS1248
Title:Minimum Standard for Gaseous Oxygen Pressure Reducers
Issuing Committee:A-10 Aircraft Oxygen Equipment Committee
Scope: 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).
