scope:

Specifies the requirements for the design, manufacture and testing of bursting disc safety devices for cryogenic service, i.e. for operation with cryogenic fluids below -10°C in addition to operation at ambient temperature. It is a requirement of this standard that the bursting disc safety device(s) comply with prEN ISO 4126-2. In the event of conflict, the requirements of this standard take precedence over that standard. Is restricted to bursting disc safety devices not exceeding a size of DN 100 designed to relieve single phase vapours or gases. A bursting disc assembly can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixutres of gases.
