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 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 specification covers the types of oxygen masks considered satisfactory for use in commercial transport aircraft at altitudes up to 25,000 ft. The types of masks covered are:
This ARP delineates requirements for system cleanliness, test gas supply system, test stand design, environmental chamber definition, instrumentation, dynamic test equipment and testing procedures.

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.

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 SAE Aerospace Recommended Practice (ARP) provides recommended practices for the cleaning of aircraft oxygen equipment, both metallic and non-metallic articles, such as oxygen lines (tubes, hoses, etc.), components (including regulator and valve parts), cylinders, and ground-based equipment that may be used to support aircraft oxygen systems. This document also specifies work area details, methods for selecting suitable cleaning agents, cleaning methods, and test methods for verifying levels of cleanliness. The cleanliness coding scheme specified in this document provides a method for documenting minimum cleanliness level requirements and for identifying compliance.
This SAE Aerospace Recommended Practice (ARP) provides recommended practices for cleaning aircraft oxygen equipment such as tubing, pieces, parts (including regulator and valve parts), cylinders and ground-based equipment that may be used to support aircraft oxygen systems. This revision introduces a cleanliness coding scheme that can be referenced as a requirement, and/or referenced to identify compliance to meeting such a requirement. These methods may apply to gaseous and liquid oxygen equipment. This document specifies work area details, methods to select suitable cleaning agents, cleaning methods, test methods to verify cleanliness level, and methods of packaging the components and parts after cleaning. Technicians designated to clean oxygen equipment must be qualified and trained to clean oxygen equipment. This ARP is applicable to metallic and non-metallic parts.

This document specifies work area details, methods to select suitable cleaning chemicals, cleaning methods, test methods to verify cleanliness level, and methods of packaging the components and parts after cleaning. Person designated to clean oxygen equipment should be qualified and trained to clean oxygen equipment. Cleanliness levels achieved are strongly dependent on the capabilities of the persons performing the cleaning operation.
This aerospace standard (AS) defines the requirements of portable protective breathing equipment for use during smoke/fire conditions on board an aircraft.
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).
