Cryogenic vessels. Safety devices for protection against excessive pressure - Safety valves for cryogenic serviceWhat is BS EN 13648 1 Safety valves for cryogenic service about? BS EN 13648 1 is a technical specification that specifies the requirements for the design, manufacture, and testing of safety valves for cryogenic service, that is to say for operation with cryogenic fluids (as defined in EN 1251 1) below 10 C in addition to operation at ambient temperature. BS EN 13648 1 requires that the valves comply with EN ISO 4126 1 or EN ISO 4126 4. In the event
