Full title and description

Space systems — Oxygen safety — Part 4: Hazards analyses for oxygen systems and components. This International Standard provides a process for conducting hazards analyses on parts, components and systems that operate in oxygen or oxygen-enriched environments and identifies processes applicable to ground support equipment, launch vehicles and spacecraft.

Abstract

ISO 22538-4:2007 defines a hazards-analysis process tailored to oxygen and oxygen-enriched atmospheres in space-system contexts. It outlines the approach to identify, assess and document hazards associated with oxygen systems and their components, with the aim of supporting safe design, operation and maintenance for ground support, launch and in-flight systems.

Scope

ISO 22538-4:2007 applies to hazards analyses for oxygen systems and components used in space-related environments. It addresses methods to identify and assess fire, ignition and other oxygen-related hazards for parts, components and complete systems, and specifies the analysis processes that may be applied to ground support equipment, launch vehicles and spacecraft. The standard is intended to be used as part of the safety and design lifecycle for oxygen-handling systems.

Key topics and requirements

• Procedure and process steps for conducting hazards analyses specific to oxygen and oxygen-enriched environments.
• Identification and assessment of ignition and combustion risks associated with oxygen systems and components.
• Applicability to parts, components and full system architectures in ground support, launch and spacecraft contexts.
• Documentation, reporting and traceability requirements for hazard findings to support design and safety reviews.
• Integration with material-selection and design guidance provided in companion parts of the ISO 22538 series.

Typical use and users

Engineers and safety specialists in aerospace manufacturers and agencies use this standard during design, verification and operations planning for oxygen systems. Typical users include spacecraft and launch-vehicle systems engineers, propulsion and life-support designers, ground-support equipment teams, hazard-analysis and safety-assurance personnel, and regulatory or certification authorities assessing oxygen-system safety.

Related standards

FAQ

Q: What is this standard?

A: ISO 22538-4:2007 is an International Standard that specifies a process for conducting hazards analyses for oxygen systems and components in space-system contexts (ground support, launch vehicles and spacecraft).

Q: What does it cover?

A: It covers the methodology for identifying and assessing hazards related to oxygen and oxygen-enriched atmospheres, including ignition and combustion risks for parts, components and systems, and the documentation of analysis results to support safe design and operations.

Q: Who typically uses it?

A: Aerospace systems engineers, safety and hazard analysts, ground-support and operations staff, material-selection specialists and certification/regulatory reviewers working on oxygen-handling systems in space and launch environments.

Q: Is it current or superseded?

A: The 2007 edition (Edition 1) remains the published version; ISO records show the publication was last reviewed and confirmed during subsequent systematic reviews (notably confirmed in 2016), so the standard remains in force unless formally revised or withdrawn by ISO.

Q: Is it part of a series?

A: Yes — ISO 22538 is a multipart series on oxygen safety for space systems; Part 1 covers design, Part 2 covers selection of metallic materials and Part 3 covers selection of non-metallic materials, which together complement the hazards-analysis guidance in Part 4.

Q: What are the key keywords?
