(Main)Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 6: Hydrants
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.
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.
Armaturen für die Wasserversorgung - Anforderungen an die Gebrauchstauglichkeit und deren Prüfung - Teil 6: Hydranten
Diese Europäische Norm legt die Mindestanforderungen an die Gebrauchstauglichkeit von Hydranten fest, die
in oberirdisch oder erdverlegten Rohrleitungssystemen für die Wasserversorgung verwendet werden oder mit
denen verbunden sind (siehe EN 805), die Wasser für den menschlichen Gebrauch führen.
Diese Europäische Norm legt die Anforderungen an die Konstruktion und die Gebrauchstauglichkeit sowie
das Konformitätsbewertungsverfahren für Hydranten fest, unabhängig von ihrer Bauart, den Werkstoffen und
ihren Aufgaben. Werden Hydranten für Feuerlöschzwecke, zur Bewässerung oder andere Aufgaben
verwendet, können zusätzliche Anforderungen in anderen Normen festgelegt sein.
Dieser Teil von EN 1074 behandelt Anforderungen, die für die Unterflur- und Überflurhydranten mit DN 65 bis
DN 150 und PFA bis 16 bar gelten.
Dieser Teil von EN 1074 enthält keine Anforderungen an die Abgänge oder deren Anschlussschnittstellen mit
den Hydranten, da diese nationalen Normen unterliegen.
Robinetterie pour l'alimentation en eau - Prescriptions d'aptitude a l'emploi et vérifications s'y rapportant - Partie 6: Poteaux et bouches
La présente Norme européenne définit les prescriptions minimales d’aptitude à l’emploi des poteaux et bouches à
utiliser dans, ou connectés à, des réseaux d’alimentation en eau aériens ou enterrés (voir EN 805), véhiculant des
eaux destinées à la consommation humaine.
La présente norme spécifie les prescriptions de conception, les prescriptions de performance, ainsi que la méthode
d’évaluation de la conformité des poteaux et bouches, quels que soient leur type, leurs matériaux et leurs fonctions.
Des prescriptions supplémentaires peuvent être données dans d’autres normes lorsque les poteaux et bouches
sont utilisés pour la lutte contre l’incendie, l’irrigation ou toute autre fonction.
La présente partie de l’EN 1074 traite des prescriptions applicables à la fois aux bouches et aux poteaux, de
dimensions DN 65 à DN 150, et de PFA jusqu’à 16 bar.
La présente partie de l’EN 1074 ne spécifie aucune prescription relative aux orifices de sortie ou aux interfaces
avec les poteaux et bouches car ils relèvent de normes nationales.

EN 1074-6:2008 (E) 3 Foreword This document (EN 1074-6:2008) has been prepared by Technical Committee CEN/TC 69 “Industrial valves”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2008, and conflicting national standards shall be withdrawn at the latest by November 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1074-6:2004. The following technical changes were made to take into account the publication of EN 14339:2005 and EN 14384:2005: Clause 1 : deletion of the sentence stating that EN 1074-6 is a priority standard; Clause 3: addition of the definition of draining system depth; Clause 4: addition of a requirement on sealing material; Subclauses 5.1.4 and 5.2.3: deletion of pillar hydrants from Table 2 and addition of a reference to EN 14384:2005; Table 3: addition of draining system depth Pv. EN 1074 consists of six parts: Part 1: General requirements; Part 2: Isolating valves; Part 3: Check valves; Part 4: Air valves; Part 5: Control valves; Part 6: Hydrants. Part 1, in conjunction with the subsequent parts, lays down the general requirements and test procedures to be carried out in production and during the assessment of conformity of these valves (type tests). The detailed requirements, which depend on the types of valves, are defined in parts 2 to 6 of this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 1074-6:2008 (E) 4 Introduction This update results from the publication of EN 14339:2005 and EN 14384:2005 which are harmonised under CPD. Thus EN 1074-6 cannot be a priority standard. As the test of EN 1074-6 are currently used by EN 14339:2005 and EN 14384:2005, the test values have been aligned with these European Standards to prevent any ambiguous interpretation. In respect of potential adverse effects on the quality of water intended for human consumption caused by the product covered by this European Standard: 1) this European Standard provides no information as to whether the product can be used without restriction in any of the Member States of the EU or EFTA; 2) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.
