Bibliography
Gives requirements for gas/materials compatibility for cryogenic vessels (such as chemical resistance) but it does not cover mechanical properties (e.g., for low temperature application). It also gives guidance for compatibility with gases other than oxygen and it gives detailed requirements for oxygen and oxygen enriched atmosphere compatibility and defines the testing methods for establishing oxygen compatibility of materials (metallic and non-metallic) to be used for cryogenic vessels and associated equipment.
