适用范围：This International Standard specifies the requirements for the design, manufacture and testing of pressurerelief valves for cryogenic service, i.e. for operation with cryogenic fluids in addition to operation attemperatures from ambient to cryogenic. It is a requirement of this International Standard that the valvescomply with ISO 4126-1; in the event of different requirements, this International Standard takes precedence.This International Standard is restricted to valves not exceeding a size of DN 150 designed to relievesingle-phase vapours or gases. A valve may be specified, constructed and tested such that it is suitable foruse with more than one gas or with mixtures of gases.NOTE This part of ISO 21013 does not provide methods for determining the capacity of relief valve(s) for a particularcryogenic vessel. Such methods are provided in ISO 21013-3.
