DIN EN 13648-2:2002-09

This European Standard 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 different requirements, this standard takes precedence over that standard. This 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 mictures of gases. Note: This standard does not provide methods for determining the capacity of bursting disc safety devices for a particular cryogenic vessel. Such methods are provided in prEN 12648-3.
