Minimum Standard for Gaseous Oxygen Pressure Reducers

2018-10-29
WIP
AS1248B
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).

FITTING, UNION, BULKHEAD, BEAM SEAL, 5000 PSI

AS8461
The project scope is to develop new AS85720 only fitting configurations (5000 PSI) that are based on “dual” cert versions (both AS85421 for 4000 PSI and AS85720 for 5000 PSI). The corresponding “dual” cert parts are being revised under G3B18-23 to specify only the lower pressure AS85421 performance specification. The dual cert part configurations are driving dual QPL listings against the same part numbers. This is proving to be logistically burdensome to maintain and confusing for users that are procuring them. These new 5000 PSI only detail drawings will have a note to reference users to the revised 4000 PSI (or lower) versions.

Aluminum Alloy, Extrusions 4.4Cu - 1.5Mg - 0.60Mn (2024-T3510) Stress-Relief Stretched, Unstraightened

2018-10-28
WIP
AMS4164J
This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing.

These products have been used typically for parts subject to excessive warpage during machining, and for parts requiring high strength and whose fabrication does not normally involve welding, but usage is not limited to such applications.

Certain design and processing procedures may cause these extrusions to be susceptible to stress-corrosion cracking; SAE ARP 823 recommends practices to minimize such conditions.
