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 essential safety requirements of the Pressure Equipment Directive (PED) 97/23/EC have been taken into consideration and those applicable to valves are addressed in this European standard.
This European 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,
but may be used for the pressure bearing parts of safety accessories such as bodies, bonnets and covers.
NOTE 1 Safety accessories means devices designed to protect pressure equipment against the allowable limits being exceeded. Requirements for safety devices for protection against excessive pressure, such as safety valves, bursting disc safety devices, safety valves and bursting disc safety devices in combination, controlled safety pressure-relief systems (CSPRS) are defined in relevant standards for safety accessories e.g. EN ISO 4126, EN 14129.
NOTE 2 The word “valve”, be in singular or in plural, hereinafter is synonymous with all items falling within the scope of this European standard as described above.
