ISO 21010:2017

Overview

ISO 21010:2017 - Cryogenic vessels: Gas/material compatibility - defines requirements and test methods for assessing gas/material compatibility in cryogenic vessels and associated equipment. The standard focuses on materials that are or could be in contact with cryogenic fluids, giving general guidance for compatibility with gases and detailed requirements for oxygen and oxygen‑enriched atmospheres. It does not cover mechanical properties for low‑temperature applications.

Key topics and requirements

• Scope and focus

  • Compatibility criteria for materials in contact with cryogenic fluids, with emphasis on oxygen service.
  • Excludes mechanical/structural property requirements.

• Material evaluation

  • Distinguishes metallic and non‑metallic materials (plastics, elastomers, lubricants, ceramics, glasses, adhesives).
  • Notes that fully oxidized materials (e.g., ceramics, glass) present low ignition risk if uncontaminated.
  • Thin metallic materials (
