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.

Minimum Standards for Valve, High Pressure Oxygen, Cylinder Shut Off, Manually Operated

2002-03-01
CURRENT
AS1066B
This standard covers all types of manually operated high pressure oxygen, cylinder shut off valves for use in commercial aircraft. It is intended that the valve shall be attached to a pressure cylinder storing oxygen under a nominal pressure of 12.76 MPa (1850 psig) at 21 °C (70 °F). Upon opening the valve, oxygen will be permitted to discharge from the storage cylinder to the valve outlet and to other downstream components of the oxygen system. It shall also be possible to recharge the cylinder through the valve.

MINIMUM STANDARDS FOR VALVE, HIGH PRESSURE OXYGEN, CYLINDER SHUT OFF, MANUALLY OPERATED

1996-07-01
HISTORICAL
AS1066A
This standard covers all types of manually operated high pressure oxygen, cylinder shut off valves for use in commercial type aircraft. It is intended that the valve shall be attached to a pressure cylinder storing oxygen under pressure of 1800 to 2100 psig at 70 °F. Upon opening the valve, oxygen will be permitted to discharge from the storage cylinder to the valve outlet and thence to other components of the oxygen system. It shall also be possible to recharge the cylinder through the valve.

HIGH PRESSURE OXYGEN SYSTEM FILLER VALVE

1971-07-30
HISTORICAL
AS1225
This AS covers oxygen filler valves for use in aircraft to ensure safe servicing of high pressure oxygen system cylinders. The intent is that the valve shall automatically control the rate of fill such that the temperature rise in the oxygen system caused by compression heating of the gas will be within acceptable limits. In addition, the valve shall have a pressure sensitive closing valve to automatically control the final pressure for a correct amount of oxygen in the system cylinder. The pressure closing level may be manually selected by means of adjustment dials on the valve.

Minimum Standards for Valve, High Pressure Oxygen, Line Shut Off, Manually Operated

1996-07-01
HISTORICAL
AS1214A
This standard covers all types of manually operated high pressure oxygen line shut off valves utilizing either metallic or nonmetallic valve seats for use in general and commercial type aircraft. It is intended that the line valve should be installed in a position accessible in flight, when the cylinder mounted oxygen valves are not. The line shutoff valve may also be used optionally in large systems as a maintenance aid where only a portion of the system need be opened up and purged after repair or replacement of one or more parts.

This AIR indicates those dimensions, deemed critical by the manufacturer, which are required to be adhered to so that proper mating of the disconnect hose fitting with the correct disconnect be accomplished. The dimensions are critical, but not necessarily complete, in defining these fittings since there are other criteria which must also be met.

Useful Life Determination for Chemical Oxygen Generators

1988-01-01
HISTORICAL
ARP1894A
The scope of this document is to provide a guideline for the preparation of a plan for testing of inservice chemical oxygen generators to confirm their design useful life. The test program should also allow determination with a sufficient level of confidence, whether generators are suitable for further use (i.e., life extension, or if the useful life limit has been reached).

USEFUL LIFE DETERMINATION CHEMICAL OXYGEN GENERATORS

HISTORICAL
ARP1894
This document provides recommended guidelines for a comprehensive program to determine the useful life of chemical oxygen generators where useful life is defined as the sum of shelf and service life. Further, this document provides for a test program to determine with a sufficient level of confidence if the generators are suitable for further use and/or if the life limit has been reached. This program should include testing of generators of a representative sampling of a given year's production, of a particular part number, to provide a level of confidence sufficient to permit the units to be used for an additional specified time period.
