BS EN ISO 21922:2021

This standard BS EN ISO 21922:2021 Refrigerating systems and heat pumps. Valves. Requirements, testing and marking is classified in these ICS categories:

• 23.060.20 Ball and plug valves
• 27.080 Heat pumps
• 27.200 Refrigerating technology

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.
