This European standard applies to metallic valves as pressure accessories for industrial applications with a maximum allowable pressure PS greater than 0,5 bar in accordance with the European legislation for pressure equipment and specifies minimum requirements applicable to design, manufacture, testing, materials and documentation.
All relevant essential safety requirements of the European legislation for pressure equipment applicable to valves have been taken into consideration and are addressed in this standard.
This standard is not applicable to:
-
safety valve and bursting disc (a safety accessory),
-
sight glass with its frames (component of a pressure equipment) and
-
measurement chambers.
For other exclusions refer to the European legislation for pressure equipment [32].
