Crewmember Demand Oxygen Mask For Transport Category Aircraft

2016-06-09
HISTORICAL
AS8026A
This standard covers oxygen masks and breathing valves used with both panel mounted and mask mounted demand and pressure-demand oxygen regulators. Mask mounted oxygen regulators are covered under other standards, but when the mask mounted regulator incorporates an integral exhalation valve, the performance of this valve shall meet the requirements of this standard.

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 STANDARD FOR OXYGEN PRESSURE REDUCERS

1991-09-01
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 STANDARD FOR PORTABLE GASEOUS, OXYGEN EQUIPMENT

1976-02-01
HISTORICAL
AS1046A
This standard is intended to apply to that portable compressed gaseous oxygen equipment used for the administration of supplementary and/or first aid oxygen to one or more occupants of either private or commercial transport aircraft.

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.

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

1971-07-01
HISTORICAL
AS1214
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.

Minimum Standard for Portable Gaseous, Oxygen Equipment

2000-03-01
HISTORICAL
AS1046B
This standard is intended to apply to that portable compressed gaseous oxygen equipment used for the administration of supplementary and/or first aid oxygen to one or more occupants of either private or commercial transport aircraft. This standard is applicable to the following types of portable oxygen equipment: a Continuous flow; b Demand flow; 1 Straight demand 2 Diluter demand 3 Pressure demand c Combination continuous flow and demand flow.

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

2023-04-26
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.
