Minimum General Standards for Oxygen Systems

2023-05-10
CURRENT
AS861C
This standard covers all types of oxygen breathing equipment used in non-military aircraft. It is intended that this standard supplements the requirements of the detail specification or drawings of specific components or assemblies (e.g., regulators, masks, cylinders, etc.). Where a conflict exists between this standard and detail specifications, detail specifications shall take precedence.

Passenger Oxygen Mask

2021-08-11
CURRENT
AS8025A
This standard covers oronasal type masks which use a continuous flow oxygen supply. Each such mask comprises a facepiece with valves as required, a mask suspension device, a reservoir, or rebreather bag (when used), a length of tubing for connection to the oxygen supply source, and a means for allowing the crew to determine if oxygen is being delivered to the mask. The assembly shall be capable of being stowed suitably to meet the requirements of its intended use.

Personal Protective Devices for Toxic and Irritating Atmospheres Air Transport Flight Deck (Sedentary) Crewmembers

2020-09-03
WIP
AS8031B
This SAE Aerospace Standard (AS) covers any protection system that serves the stated purpose. This document establishes minimum performance requirements for emergency equipment, which provides flight deck (sedentary) crewmembers with eye and respiratory protection from toxic atmospheres during in-flight emergencies. Defintion of sedentary: "sedentary" is herein defined as those flight deck crewmembers that remain seated at their flight deck stations throughout the emergency. For those "nonsedentary" cabin crewmembers whose duty it is to leave their flight station during an emergency (for example, to actively locate and fight an on-board fire).

Minimum Standard for Gaseous Oxygen Pressure Reducers

2020-05-27
CURRENT
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).

Oxygen Cylinder Quality, Serviceability, Maintenance Transfilling, and Marking

2020-01-17
CURRENT
AIR1059F
This document provides guidance concerning the maintenance and serviceability of oxygen cylinders beginning with the quality of oxygen that is required, supplemental oxygen information, handling and cleaning procedures, transfilling, and marking of serviced oxygen assemblies. This document attempts to outline in a logical sequence oxygen quality, serviceability, and maintenance of oxygen cylinders. Content of this document can also be used for refilling of oxygen cylinder while installed on aircraft, directly or through an intermediate charging port.

Chemical Oxygen Supplies

2014-10-30
CURRENT
AIR1133B
Solid chemical oxygen supplies of interest to aircraft operations are "chlorate candles" and potassium superoxide (KO2). Chlorate candles are used in passenger oxygen supply units and other emergency oxygen systems, such as submarines and escape devices. Potassium superoxide is not used in aircraft operations but is used in closed-cycle breathing apparatus. Characteristics and applications of both are discussed, with emphasis on chlorate candles.
