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.<\/p>\n
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.<\/p>\n
This standard is not applicable to:<\/p>\n
safety valve and bursting disc (a safety accessory),<\/p>\n<\/li>\n
sight glass with its frames (component of a pressure equipment) and<\/p>\n<\/li>\n
measurement chambers.<\/p>\n<\/li>\n<\/ul>\n
For other exclusions refer to the European legislation for pressure equipment [32].<\/p>\n
