标准范围

ISO 21013规定了低温环境下减压阀的设计、制造和测试要求，即除了在环境温度到低温温度下工作外，还应在低温流体中工作。ISO 21013要求阀门符合ISO 4126-1；如果有不同的要求，则以ISO 21013为准。ISO 21013仅限于尺寸不超过DN 150的阀门，用于释放单相蒸汽或气体。可对阀门进行规定、构造和测试，以使其适用于多种气体或混合气体。ISO 21013-1:2008未提供确定特定低温容器安全阀容量的方法。ISO 21013-3中提供了此类方法。

ISO 21013 specifies the requirements for the design, manufacture and testing of pressure relief valves for cryogenic service, i.e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic. It is a requirement of ISO 21013 that the valves comply with ISO 4126-1; in the event of different requirements, ISO 21013 takes precedence.ISO 21013 is restricted to valves not exceeding a size of DN 150 designed to relieve single-phase vapours or gases. A valve may be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases.ISO 21013-1:2008 does not provide methods for determining the capacity of relief valve(s) for a particular cryogenic vessel. Such methods are provided in ISO 21013-3.
