This part of BS EN ISO 28921 specifies requirements for the design, dimensions, material, fabrication and production testing of isolated valves for low temperature applications.

It applies to gate, globe, check, butterfly, and ball valves and can be used for other valve types used in low temperature services.

This part is ISO 28921 covers isolation valves for use in cryogenic temperature service where the design low temperature service is -50°C down to -196°C.

It does not apply to valves for cryogenic services, designed in accordance with BS ISO 21011, used with cryogenic vessels.
