Minimum General Standards for Oxygen Systems
2023-05-10
CURRENT
AS861C
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.

Testing of Oxygen Equipment
2021-08-11
CURRENT
ARP1398A
This ARP delineates requirements for system cleanliness, test gas supply system, test stand design, environmental chamber definition, instrumentation, dynamic test equipment and testing procedures.
Standard

Passenger Oxygen Mask
2021-08-11
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.

Oxygen Sensor Technologies
2020-12-18
CURRENT
AIR5933
AIR5933 provides an overview of contemporary technologies (i.e., sensors) that measure the proportion of oxygen in a gas. The use of these sensors in the aerospace environment, with its special constraints, is discussed and papers/reports with detailed information are summarized and referenced. The sensors are divided into expendable and non-expendable sensors. Expendable sensors are based on electrochemical properties, whereas non-expendable sensors rely on paramagnetic, photo-acoustic, electromagnetic, and laser spectroscopy properties.

Oxygen System and Component Cleaning
2020-10-19
CURRENT
ARP1176B
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.

Personal Protective Devices for Toxic and Irritating Atmospheres Air Transport Flight Deck (Sedentary) Crewmembers
2020-09-03
WIP
AS8031B
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).

Lubricants for Oxygen Use
2020-07-14
CURRENT
AIR4071A
This SAE Aerospace Information Report (AIR) describes two classes of lubricants which, when properly applied, can be used in oxygen systems and components.

Minimum Standard for Gaseous Oxygen Pressure Reducers
2020-05-27
CURRENT
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).

Oxygen Cylinder Quality, Serviceability, Maintenance Transfilling, and Marking
2020-01-17
CURRENT
AIR1059F
This document provides guidance concerning the maintenance and serviceability of oxygen cylinders beginning with the quality of oxygen that is required, supplemental oxygen information, handling and cleaning procedures, transfilling, and marking of serviced oxygen assemblies. This document attempts to outline in a logical sequence oxygen quality, serviceability, and maintenance of oxygen cylinders. Content of this document can also be used for refilling of oxygen cylinder while installed on aircraft, directly or through an intermediate charging port.

Oxygen Cylinder Installation Guide
2019-04-11
CURRENT
ARP5021B
This document provides guidance for oxygen cylinder installation on commerical aircraft based on airworthiness requirements, and methods practiced within aerospace industry. 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.

Oxygen Flow Indication
2019-01-10
CURRENT
AS916C
This SAE Aerospace Standard (AS) defines the overall requirements applicable to oxygen flow indication as required by Airworthiness Requirements of CS/FAR 25.1449 to show that oxygen is being delivered to the dispensing equipment. Requirements of this document shall be applicable to any type of oxygen system technology and encompass “traditional” pneumatic devices, as well electric/electronic indication.

HISTORICAL
ARP1176A
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.
