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.
