HISTORICAL
AIR825/5
This Aerospace Information Report provides general information to aircraft designers and engineers, regarding LOX, its properties, its storage and its conversion to gas. Much useful information is included herein for aircraft designers regarding important design considerations for a safe and effective installation to an aircraft. The associated ground support equipment needed to support operations of LOX equipped aircraft is also discussed. It is important to realize that LOX equipped aircraft cannot be supported unless this support infrastructure is also available. A significant part of this document will address the specific advantages, disadvantages and precautions relating to LOX systems. These are important issues that must be considered in deciding which oxygen system to install to the aircraft. Also, many commercial and military aircraft use aeromedical LOX equipment that is mostly portable equipment.

Oxygen System Fill/Check Valve

1997-12-01
CURRENT
AS1225A
This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's Specification for Requirements which are beyond the scope or level of detail provided in this document. One valve has an adjustable pressure sensitive closing valve to automatically control the final pressure for a correct amount of oxygen in the system. The second valve incorporates an automatic shutoff feature designed to limit system overpressurization in the event maintenance personnel do not stop system filling at the correct pressure. The intent of the fill valves is to control the rate of fill to limit the rise in temperature caused by compression heating to acceptable values, prevent oxygen back flow and prevent the ingestion of foreign matter that could cause contamination of the system.

MINIMUM STANDARD FOR OXYGEN PRESSURE REDUCERS

1973-05-01
HISTORICAL
AS1248
This standard is designed to cover all types of pressure reducers required for oxygen systems and for all performance profiles without regard for a particular inlet pressure or outlet pressure performance curve. Special attention will be given, however, to construction requirements essential in reducers where critical high initial oxygen pressures such as 1850 to 2250 psig (12.76 to 15.51 MN/m2 gauge) at 70° F (21.1° C) are involved.
