Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 6: Hydrants

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 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 (e.g. prEN 14339:2001).
This standard applies in priority to any other product or test standard. The requirements from other standards apply only when this European Standard refers to them.
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.

Robinetterie pour l'alimentation en eau - Prescriptions d'aptitude a l'emploi et vérifications s'y rapportant - Partie 6 : Poteaux et bouches

Cette partie 6 fixe les spécifications et contrôles applicables aux poteaux et bouches de pression nominale PN 10 - PN 16 et dont les diametres nominaux sont ceux définis dans la partie 1, limités au DN 150, il s'agit du diametre nominal de raccordement a la canalisation. Les essais de Type doivent etre réalisés sur tous les DN pour les poteaux et bouches. Par ailleurs, si une robinetterie de sectionnement est associée a ces appareils, pour une telle configuration, la partie 2 de la présente norme s'applique.
