GSO EN 1074-4:2014 Scope
This European Standard specifies the minimum fitness for purpose requirements for valves to be used in, or connected to, water supply pipe systems above or below ground (see EN 805), carrying water intended for human consumption. This standard specifies the design requirements, the performance requirements, and the conformity assessment method for valves, whatever their type and materials. This standard applies in priority to any other product or test standard : the requirements from other standards apply only when this standard refers to them. This standard deals with the requirements applicable to air valves with DN up to DN 300 and PFA 6 to PFA 25.
