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.

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 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 Information Report (AIR) provides an orientation regarding the general technology of chemical oxygen generators to aircraft engineers for assistance in determining whether chemical oxygen generators are an appropriate oxygen supply source for hypoxia protection in a given application and as an aid in specifying such generators. Information regarding the details of design and manufacture of chemical oxygen generators is generally beyond the scope of this document.
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.
Closed-cycle protective breathing apparatus, commonly referred to as rebreathers, or CCBA provide trained aircrew members or ground personnel with eye and respiratory protection from toxic atmospheres.
This SAE Aerospace Information Report (AIR) provides general information on Continuous Flow Oxygen Systems which are available, principle functions of those systems and technical approaches to be taken into account during design and realization of systems. However, particular performance specifications and detailed information of manufacturing, testing and integration of such systems is beyond the scope of this document.
This slash document collects general reference material related to gaseous oxygen system flow requirements and sizing calculations. This document will assist oxygen system equipment designers and operators to establish systems and equipment requirements. The document consists of charts, tables, system schematics, system requirements, and sample calculations for system sizing.
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 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.
