40、N 16668:2016 (E) 6 1 Scope 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 2014/68/EU and specifies minimum requirements applicable to d
41、esign, manufacture, testing, materials and documentation. All relevant essential safety requirements of the Pressure Equipment Directive 2014/68/EU applicable to valves have been taken into consideration and are addressed in this standard. This standard is not applicable to: safety valve and burstin
