标准范围

ISO 21013-2:2007规定了用于低温服务的不可再闭合泄压装置的设计、制造和测试要求，即除了在环境温度到低温温度下运行外，还可使用低温流体运行。ISO 21013-2:2007仅适用于尺寸不超过DN 200的爆破片和屈曲销装置，用于释放单相蒸汽或气体。爆破片或屈曲销组件的规定、构造和测试应确保其适用于多种气体或混合气体。ISO 21013-2:2007未提供确定特定低温容器爆破片或屈曲销装置容量的方法。ISO 21013-3中提供了此类方法。

ISO 21013-2:2007 specifies the requirements for the design, manufacture and testing of non？reclosable pressure？relief devices for cryogenic service, i.e. for operation with cryogenic fluids in addition to operation at temperatures from ambient to cryogenic.ISO 21013-2:2007 is restricted to bursting？disc and buckling？pin devices not exceeding a size of DN 200 designed to relieve single？phase vapours or gases. A bursting？disc or buckling？pin assembly may be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases.ISO 21013-2:2007 does not provide methods for determining the capacity of bursting disc or buckling pin devices for a particular cryogenic vessel. Such methods are provided in ISO 21013-3.
