It covers considerations for oxygen systems from beginning of project phase up to production, maintenance, and servicing. The document is related to requirements of DOT-approved oxygen cylinders, as well to those designed and manufactured to standards of ISO 11119. However, its basic rules may also be applicable to new development pertaining to use of such equipment in an oxygen environment. For information regarding oxygen cylinders itself, also refer to AIR825/12

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 and complies with the United States Pharmacopoeia (USP). In Europe, medical oxygen specification compiles with the European Pharmacopoeia monograph (Ph

These recommendations are to aid the international air transport industry by identifying a standard, minimum amount of safety instructions and procedures that should be provided in the PSIS. Aircraft operators are encouraged to customize the PSIS to their own operations. This document also provides recommendations for: a Passenger safety information briefings and associated materials, b Demonstration emergency equipment, c Ensuring passenger suitability for those seated in exit seats, d The standardization of safety briefings for passengers seated at exits who may be responsible for opening exits on transport aircraft during an emergency, and e A standardized protective brace position to reduce the severity of injury during severe turbulence, rapid deceleration, or a sudden impact. In addition, these recommendations pertain to briefings on aircraft on which the cabin crew would conduct the exit seat briefing, and to briefings on aircraft without cabin crew, on which pilots would
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
There are four basic conditions requiring the dispensing of oxygen through oxygen masks to aircraft occupants in turbine powered aircraft during flight. The following conditions are derived from the Federal Aviation Regulations (FAR) as listed in Section 2
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
This specification covers the requirements for two types of oxygen pressure reducers
This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's Specification for Requirements which are beyond the scope or level of detail provided in this document. One valve has an adjustable pressure sensitive closing valve to automatically control the final pressure for a correct amount of oxygen in the system. The second valve incorporates an automatic shutoff feature designed to limit system overpressurization in the event maintenance personnel do not stop system filling at the correct pressure. The intent of the fill valves is to control the rate of fill to limit the rise in temperature caused by compression heating to acceptable values, prevent oxygen back flow and prevent the ingestion of foreign matter that could cause contamination of the system. Note
This SAE Aerospace Recommended Practice (ARP) provides design, operation, construction, test and installation recommendations for equipment that automatically presents supplemental oxygen masks to cabin occupants in the event of loss of cabin pressure. It specifically covers automatic presentation for transport category aircraft that operate above 30 000 ft (9144 m) altitude. It also provides guidance for similar equipment used in non-transport category aircraft, or aircraft operated below 30 000 ft (9144 m) altitude
The scope of this document is related to the particular needs of oxygen equipment with regards to packaging and transportation. The document provides guidance for handling chemical, gaseous and liquid oxygen equipment.
