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.

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).

This standard covers both general type and quick-donning type mask assemblies in the following classes: a Class A, oronasal, demand b Class B, oronasal, pressure-demand c Class C, full face, demand d Class D, full face, pressure-demand

This Aerospace Standard (AS) provides recommended design guidelines for composition formation, performance, testing and reliability of metal-chlorate-perchlorate class solid chemical oxygen generators, supplying oxygen at essentially ambient pressure, for aircraft whose cabin pressure altitude does not exceed 40,000 feet (12,192 m).

This Aerospace Information Report (AIR) specifies work area details, cleaning methods, test methods, and specifications for oxygen clean parts and packaging materials.

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. Applicability: When this standard is specified in an acquisition document, the applicable requirements of this standard that apply to the acquisition document shall be identified. Application guidance: Certain provisions of this standard and the manufacturer's cleaning inspection and packaging procedures may differ due to oxygen equipment complexity of construction, material, etc. These differences shall be identified in the acquisition document with a determination of what is acceptable; the provisions of this standard, the manufacturer's procedure, or a specified acceptable alternate, as applicable.
