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.

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.

The aim of this document is to summarize information on packaging and transportation of oxygen equipment. Statements and references to regulations cited herein are for information only and should not be considered as interpretation of a law. Processes to maintain cleanliness of components and subassemblies during processing and assembly or storage of work-in-progress are outside the scope of this document. Guidance on this can be obtained from ARP1176.

CURRENT

AIR5933

AIR5933 provides an overview of contemporary technologies (i.e., sensors) that measure the proportion of oxygen in a gas. The use of these sensors in the aerospace environment, with its special constraints, is discussed and papers/reports with detailed information are summarized and referenced. The sensors are divided into expendable and non-expendable sensors. Expendable sensors are based on electrochemical properties, whereas non-expendable sensors rely on paramagnetic, photo-acoustic, electromagnetic, and laser spectroscopy properties.

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).

Fuel Versus Oxygen: Evaluations and Considerations

2018-10-18

CURRENT

AIR5648A

Specific federal aviation regulations (Titled 14 of the United States Code of Federal Regulations, or 14 CFR) define oxygen system requirements for an in-flight decompression incident. This AIR addresses the operational oxygen system requirements for a decompression incident that may occur at any point during a long-range flight, with an emphasis for a decompression at the equal time point (ETP). This AIR identifies fuel and oxygen management contingencies, and presents possible solutions for the efficient, safe, and optimum fuel/oxygen flight continuation. Oxygen management is a concern to all aircraft, such as single engine types that fly above 10 000 feet and use supplemental oxygen. This document provides a method which can help guide users in developing an oxygen solution for their aircraft.

HISTORICAL

AS1248A

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).

Aviator's Breathing Oxygen Purity Standard

2012-10-18

HISTORICAL

AS8010C

This document defines the minimum degree of purity and maximum levels of certain deleterious impurities allowable for aviator's breathing oxygen at the point of manufacture or generation. It covers gaseous, liquid, and chemically generated oxygen, and oxygen supplied by in situ concentration and in situ electrolysis. Different limits are established for oxygen from different sources, in recognition of differences in the ways the oxygen is stored, dispensed, and utilized, taking into account the safety of the user. These limits are not intended to specifically reflect upon the relative capabilities or merits of various technologies. Procurement documents may specify more stringent limits, where required for specific applications. Medical oxygen is not covered by this standard. In the United States, medical oxygen is a prescription drug.
