    Abstract - (Show below) - (Hide below)

    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 Pressure Equipment Directive (PED) 97/23/EC and specifies minimum requirements applicable to design, manufacture, testing, materials and documentation.All relevant essential safety requirements of the Pressure Equipment Directive (PED) 97/23/EC 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 PED.
