This European Standard specifies 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 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.
It mainly deals with materials that are normally or could be in contact with liquid/gaseous oxygen e.g., materials for cryogenic vessels used for the storage and/or transport of liquid oxygen.
It also deals with the materials which can be in contact with oxygen enriched environment e.g. insulating materials used for nitrogen, neon, hydrogen and helium cryogenic vessels in case of air condensation.
