scope:
Specifies the requirements for the design, manufacture and testing of safety valves for cryogenic service, i.e. for operation with cryogenic fluids below -10°C in addition to operation at ambient temperature. It is a requirement of this standard that the valves comply with prEN ISO 4126-1. In the event of conflict, the requirements of this standard take precedence over that standard. Is restricted to valves not exceeding a size of DN 100 designed to relieve single phase vapours or gases. A valve can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases.
