Full title and description

ISO 22538-1:2007 — Space systems — Oxygen safety — Part 1: Design of oxygen systems and components. This part of ISO 22538 provides a structured process and design guidance for oxygen systems and their components used in space applications, including ground support equipment, launch vehicles and spacecraft.

Abstract

Describes a process for the design of oxygen systems and their components, addressing safety principles to reduce ignition and fire risk in oxygen-enriched environments. The guidance in this part applies equally to ground support equipment, launch vehicles and spacecraft.

Scope

This part of ISO 22538 specifies a design process and safety-related design considerations for oxygen systems and components used in space contexts. It covers system-level design objectives to reduce oxygen-related fire and ignition hazards and is applicable to ground support equipment, launch vehicles and spacecraft.

Key topics and requirements

• Structured design process for oxygen systems (hazard identification and mitigation).
• Design rules to minimise ignition sources and to limit fire propagation in oxygen-enriched environments.
• Material and component selection practices and cross-reference to material-selection parts of the series.
• Cleaning, contamination control and assembly practices for oxygen service.
• Pressure, flow and containment considerations specific to oxygen systems.
• Testing, inspection, verification and documentation requirements for safety assurance.
• Requirements for maintenance, repair and traceability of oxygen-system components.

Typical use and users

Used by spacecraft and launch-vehicle systems designers, propulsion and life-support engineers, materials and components engineers, safety and systems‑engineering teams, test laboratories, procurement and quality assurance staff, and agencies/organizations responsible for certification and accident‑prevention in aerospace programs. Guidance in this standard is consistent with other aerospace oxygen safety practices used by organizations such as NASA.

FAQ

Q: What is this standard?

A: ISO 22538-1:2007 is the first part of an ISO series addressing oxygen safety for space systems, providing design guidance for oxygen systems and their components used in space applications.

Q: What does it cover?

A: It covers a structured design process and safety considerations (including mitigation of ignition and fire risks) for oxygen systems used in ground support, launch vehicles and spacecraft; it also points to material-selection parts of the series for component‑level guidance.

Q: Who typically uses it?

A: Aerospace designers and engineers (systems, propulsion, life‑support), materials engineers, safety engineers, test houses, procurement and QA teams, and agencies that evaluate and certify space hardware.

Q: Is it current or superseded?

A: The published 2007 edition was reviewed and confirmed in subsequent systematic reviews; the ISO record indicates it was last reviewed/confirmed (remains current as issued). Users should check the ISO catalogue for any revision notices before use.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 22538 series. Part 2 addresses selection of metallic materials and Part 3 addresses selection of non‑metallic materials for oxygen systems and components.
