Cryogenic vessels — Pressure-relief accessories for cryogenic service — Part 2: Non-reclosable pressure-relief devices
Description
This document 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.
This document is restricted to bursting‑disc and buckling‑pin devices not exceeding a nominal diameter size (DN) of 200 that are designed to relieve single‑phase vapours or gases. A bursting‑disc or buckling‑pin assembly can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases.
NOTE This document 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.

A bursting‑disc or buckling‑pin assembly can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases.
