This document specifies the requirements for the design, manufacture and testing of pressure relief valves for cryogenic service, i.e. for operation with cryogenic fluids below -10 °C in addition to operation at ambient temperatures from ambient to cryogenic. It is a requirement of this International Standard that the valves comply with ISO 4126-1; in the event of different requirements, this International Standard takes precedence over that standard.

This document 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.

NOTE

This part of ISO 21013 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.
