BS EN 13648-1:2008 Cryogenic vessels. Safety devices for protection against excessive pressure. Safety valves for cryogenic service

BS EN 13648-1 specifies the requirements for the design, manufacture and testing of safety valves for cryogenic service. It specifically applies to valves for operation with cryogenic fluids below – 10 °C in addition to operation at ambient temperature.

BS EN 13648-1 requires that valves comply with EN ISO 4126-1 or EN ISO 4126-4. In the event of different requirements, the requirements for cryogenic service are applied.

BS EN 13648-1 is restricted to valves not exceeding a size of DN 100 for category B. The valves of category A are limited to DN 25 and set pressures up to 40 bars. Both categories are designed to relieve single phase vapours or gases.

A valve can be specified, constructed and tested such that it is suitable for use with more
than one gas or with mixtures of gases. All safety valves covered in this European Standard correspond to category IV of PED (Directive 97/23/EC) and category 3 of TPED (Directive 99/36/EC).

BS EN 13648-1 does not provide methods for determining the capacity of relief valve(s) for a particular cryogenic vessel. Such methods are provided in EN 13648-3.
