Describes the minimum fitness for purpose requirements for hydrants to be used in, or connected to, water supply pipe systems, above or below ground, carrying water intended for human consumption.

This European Standard defines the minimum fitness for purpose requirements for hydrants 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 European Standard specifies the design requirements, the performance requirements, and the conformity assessment method for hydrants, whatever their type, materials and functions. Where hydrants can be used for fire fighting, irrigation or other function, additional requirements can be given in other standards. This part of EN 1074 deals with the requirements applicable to both underground and pillar hydrants, in sizes DN 65 to DN 150, and PFA up to 16 bar. This part of EN 1074 does not give requirements for the outlets or their interface with the hydrants, since they are subject to national standards.
