Optionally co-design standards:
This European standard specifies safety requirements, safety factors, test methods, test pressures used and
marking of refrigerating valves and other components with similar bodies, hereinafter called valves, for use in
refrigerating systems.
It describes the procedure to be followed when designing (by calculation or by an experimental design method)
valve parts subjected to pressure as well as the criteria to be used in the selection of materials.
The standard describes methods by which reduced impact values at low temperatures may be taken into account
in a safe manner.
This standard applies to the design of bodies and bonnets for pressure relief devices, including bursting disc
devices, with respect to pressure containment but it does not apply to any other aspects of the design or application
of pressure relief devices.
