FAR – Regulatory Requirements Covering the Use of Breathing Oxygen in Aircraft

2016-06-22
CURRENT
AIR1389B
This report presents, paraphrased in tabular format, an overview of the Federal Aviation Regulations (FAR) for aircraft oxygen systems. It is intended as a ready reference for those considering the use of oxygen in aircraft and those wishing to familiarize themselves with the systems requirements for existing aircraft. This document is not intended to replace the oxygen related FAR but rather to index them in some order. For detailed information, the user is referred to the current issue of the relevant FAR paragraph referenced in this report.

HISTORICAL
AS1304
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).

MINIMUM STANDARD FOR OXYGEN PRESSURE REDUCERS

1973-05-01
HISTORICAL
AS1248
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.

AS1248B
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).

Chemical Oxygen Supplies

1991-04-15
HISTORICAL
AIR1133A
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.

AIR6190A
This document provides information on provisions for passengers with disabilities on board commercial aircraft. In this context the term "provision of medical oxygen" shall be understood as application of oxygen on board an aircraft not linked to (post) decompression in the sense of Airworthiness Requirements FAR/CS 25 and Operational Regulations of FAR 121/135. Information about available equipment and physiological treatment in clinical practice will be provided in this document. It covers the use of oxygen concentrators according to guidance of FAR Advisory Circular AC120-95.

USEFUL LIFE DETERMINATION CHEMICAL OXYGEN GENERATORS

1987-02-01
HISTORICAL
ARP1894
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.

CURRENT
AS8025A
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.
