This Aerospace Recommended Practice (ARP) describes test equipment and methods used for testing closed cycle or semi closed cycle breathing devices of short duration that are designed to operate with a high partial pressure of oxygen in the breathing circuit. It is intended to supplement ARP1109 and ARP1398 for applications involving closed cycle or semiclosed cycle breathing equipment which may be evaluated to the requirements of AS8031 and/or AS8047.
The purpose of this document is to provide minimum requirements for cleaning aircraft breathing oxygen systems and components, inspection methods and packaging after cleaning, and guidelines for oxygen equipment cleaning areas.
This document covers information concerning the use of oxygen when flying into and out of high elevation airports for both pressurized and non-pressurized aircraft. Oxygen requirements for pressurized aircraft operating at high altitudes have for decades emphasized the potential failures that could lead to a loss of cabin pressurization coupled with the potential severe hypoxic hazard that decompressions represent. This document is intended to address the case where the relationship between cabin and ambient pressures are complicated by operations at high terrestrial altitudes. Operators who fly into these high-altitude airports should address the issues related to this environment because it carries the potential for insidious hypoxia and other conditions which can affect safety. It provides information to consider in developing operational procedures to address hypoxia concerns consistent with regulatory mandates.
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.
This specification applies to a chemical oxygen generator assembly for the following uses: a First aid treatment of passenger cabin occupants after emergency descent in a turbine engine powered airplane with pressurized cabin, as specified in FAR 121.333, Para. e (3). b By cabin attendants to maintain their mobility after cabin decompression.
This SAE Aerospace Standard (AS) applies to a portable chemical oxygen generator assembly intended for the following uses: a First aid treatment of aircraft occupants after an emergency descent following a decompression or other emergency condition. b Use by cabin attendants to maintain their mobility after a decompression.

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.

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).
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.

This standard is intended to establish general material and design requirements for oxygen flow indicating devices. Flow indicators considered are for diluter-demand and continuous flow systems.
