Full title and description

SAE AS8025A-2021 — Passenger Oxygen Mask. This SAE Aerospace Standard defines requirements for oronasal-type passenger oxygen masks that use a continuous-flow oxygen supply, covering the mask facepiece and valves, suspension device, reservoir/rebreather bag (when used), connecting tubing, and means to indicate that oxygen is being delivered; it also addresses stowage appropriate to the intended use.

Abstract

This standard specifies construction, functional and performance requirements, and related test/inspection considerations for passenger supplemental oxygen masks used in transport-category aircraft. It focuses on continuous-flow oronasal mask assemblies intended for use by untrained cabin occupants, including provisions for oxygen flow indication and stowage.

Scope

The scope covers oronasal type masks using continuous-flow oxygen supplies intended for passenger use. It applies to the assembled mask (facepiece, required valves, suspension device), any reservoir or rebreather bag when used, connecting tubing, and an indication means to allow crew or occupants to determine that oxygen is being delivered. The document also addresses stowage and suitability for the mask’s intended installation and use on transport-category aircraft.

Key topics and requirements

• Design and construction of oronasal (passenger) oxygen masks for continuous-flow systems.
• Valve, facepiece, suspension, reservoir/rebreather bag, and tubing requirements.
• Means for positive indication that oxygen is being delivered to the mask (flow indication).
• Stowage, deployment and installation considerations appropriate to passenger use.
• Performance and environmental test requirements to demonstrate functionality and durability.
• Marking, instructions for use, and compatibility with aircraft oxygen supply interfaces and procedures.

These topics are drawn from the standard’s scope and content summary as published by SAE.

Typical use and users

Manufacturers of aircraft passenger oxygen masks and assemblies, aircraft OEM design and systems engineers, certification and compliance teams, airline technical and procurement groups, MRO organizations, and test laboratories use AS8025A to design, certify, procure, and verify passenger supplemental oxygen mask assemblies and related installations.

Related standards

AS8025A is associated with other SAE documents and aerospace publications covering oxygen systems and passenger respiratory protective equipment, including SAE ARP4287 (automatic presentation of supplemental oxygen masks), AS8048A (performance standard for passenger smoke and toxic fumes respiratory protective equipment), and other SAE oxygen-system standards (examples: AS1225A and AS916C are cross-referenced in the broader oxygen-equipment family). These related documents provide complementary requirements for presentation mechanisms, flow indication, valves, and system components.

FAQ

Q: What is this standard?

A: SAE AS8025A-2021 is the SAE Aerospace Standard titled "Passenger Oxygen Mask" that sets design, construction, performance, and stowage requirements for continuous-flow oronasal passenger oxygen masks.

Q: What does it cover?

A: It covers the mask assembly (facepiece, valves, suspension), reservoir/rebreather bag where used, connecting tubing, and means to show oxygen delivery, plus stowage and suitability for passenger-use installations on transport-category aircraft.

Q: Who typically uses it?

A: Aircraft OEMs, mask and oxygen-equipment manufacturers, airlines (procurement and engineering), maintenance/repair organizations, certification authorities, and test laboratories use the standard for design, procurement, verification, and certification tasks.

Q: Is it current or superseded?

A: As published in SAE’s catalogue, AS8025A is listed as reaffirmed on August 11, 2021; the document history shows original issuance in 1988 and a recorded revision in 1999. That reaffirmation indicates the standard was reviewed and retained in 2021 rather than being superseded at that time. Users should confirm the current status in SAE’s standards catalogue for any updates after 2021.

Q: Is it part of a series?

A: Yes — AS8025A is part of the SAE family of aerospace oxygen- and passenger-safety-related standards and is cross-referenced by related ARP and AS documents (for example ARP4287, AS8048A, AS1225A, and AS916C), which together address presentation, flow indication, valves, and other oxygen-system components.

Q: What are the key keywords?

A: Passenger oxygen mask; oronasal; continuous-flow; oxygen flow indication; reservoir bag; aircraft oxygen equipment; emergency oxygen; SAE AS8025A.
