Ductile iron pipes, fittings, accessories and their joints for water pipelines - Requirements and test methods
This European Standard specifies the requirements and associated test methods applicable to ductile iron pipes, fittings, accessories and their joints for the construction of pipelines: - to convey water (e. g. for drinking water pipelines, fire protection, snow guns, irrigation, hydroelectric, reused water pipelines, etc…) - with or without pressure ; - to be installed below or above ground. This standard is applicable to pipes, fittings and accessories which are : - manufactured with socketed, flanged or spigot ends; - normally delivered externally and internally coated ; - suitable for fluid temperatures between 0 °C and 50 °C, excluding frost. This standard covers pipes, fittings ast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints and accessories, in a size range extending from DN 40 to DN 2 000, inclusive. This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components including joints. Joint design and gasket shapes are outside the scope of this standard. In addition reference is made to the performance requirements of couplings, flange adaptors and saddles manufactured only for use with ductile iron pipes and fittings NOTE In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).
Rohre, Formstücke, Zubehörteile aus duktilem Gusseisen und ihre Verbindungen für Wasserleitungen - Anforderungen und Prüfverfahren
Diese Europäische Norm legt die Anforderungen und die diesbezüglichen Prüfverfahren fest, die auf gusseiserne Rohre, Formstücke und ihre Verbindungen zur Errichtung von Rohrleitungen außerhalb von Gebäuden anwendbar sind:
zum Transport von Wasser (z. B. Wasser für den menschlichen Gebrauch, Brandbekämpfung, Schnee¬kanonen, Bewässerung, Wasserkraftanlagen, Rohrleitungen für wiederaufbereitetes Wasser usw.);
mit oder ohne Innendruck;
oberirdisch oder erdverlegt.
Diese Norm gilt für Rohre, Formstücke und Zubehörteile, die:
mit Muffen, Flanschen oder Einsteckenden versehen sind;
mit Umhüllung und Auskleidung geliefert werden;
für Temperaturen flüssiger Medien zwischen 0 °C, jedoch außerhalb des Frost¬bereiches, und 50 °C geeignet sind;
nicht für die Anwendung in Bereichen, die Bestimmungen zum Brandverhalten unterliegen, vorgesehen sind.
ANMERKUNG 1 Dies schließt besondere Vereinbarungen für die Verwendung dieser Produkte bei höheren Temperaturen nicht aus.
Diese Norm gilt für Rohre und Formstücke, die nach einem beliebigen Gießverfahren oder aus gegossenen Einzelteilen hergestellt werden, ebenso für die entsprechenden Verbindungen und Zubehörteile für den Nennwei¬tenbereich von DN 40 bis einschließlich DN 2000.
Diese Europäische Norm legt Anforderungen an Werkstoffe, Abmessungen und Grenzabmaße, mechanische Eigenschaften und die Standardumhüllungen und Auskleidungen von Rohren und Formstücken aus duktilem Gusseisen fest. Sie enthält ebenfalls Anforderungen an die Funktion aller Rohrleitungsteile, einschließlich der Verbindungen. Ausführung der Verbindungen und Form der Dichtungen liegen außerhalb des Anwendungs¬bereiches dieser Europäischen Norm.
Darüber hinaus wird auf die Leistungsanforderungen an Kupplungen, Flanschadapter und Sattelstücke, die für den Gebrauch mit Rohren und Formstücken aus duktilem Gusseisen hergestellt sind, Bezug genommen.
Tuyaux, raccords et accessoires en fonte ductile et leurs assemblages pour canalisations d'eau - Prescriptions et méthodes d'essai
La présente Norme européenne prescrit les exigences et les méthodes d'essai associées, applicables aux tuyaux, raccords et accessoires en fonte ductile et à leurs assemblages, destinés à la construction de canalisations situées à l'extérieur des bâtiments :
pour transporter de l'eau (par exemple de l'eau destinée à la consommation humaine, à la protection contre l'incendie, aux canons à neige, à l'irrigation, à l'hydroélectricité, aux canalisations d'eaux recyclées, etc.) ;
avec ou sans pression ;
installées dans le sol ou en aérien.
Cette norme est applicable aux tuyaux, raccords et accessoires qui sont :
fabriqués avec des extrémités à emboîture, à bride ou à bout uni ;
fournis revêtus extérieurement et intérieurement ;
utilisables pour des températures de fluide allant de 0 °C à 50 °C, gel exclus ;
non destinés à être utilisés dans des zones soumises aux réglementations relatives à l'incendie.
NOTE 1 Cela n'interdit pas des aménagements spéciaux pour les produits devant être utilisés à haute température.
Cette norme traite des tuyaux et raccords moulés par tout procédé de fonderie ou fabriqués à partir de composants moulés, ainsi que les assemblages et accessoires correspondants, pour la gamme de dimensions allant de DN 40 à DN 2000 inclus.
Cette norme prescrit les exigences pour les matériaux, les dimensions et écarts limites, les propriétés mécaniques et les revêtements standards des tuyaux et raccords en fonte ductile. Elle indique également des prescriptions de performance pour tous les composants y compris les assemblages. La conception des assemblages et la géométrie des bagues de joint ne font pas partie du domaine d'application de cette norme.
En outre, référence est faite aux prescriptions de performance relatives aux manchons, aux adaptateurs de brides et aux colliers de prise à selle fabriqués pour être utilisés avec des tuyaux et des raccords en fonte ductile.

This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EC Directive(s).
For relationship with EC Directive(s), see informative Annexes B, C, D, E, F, and G, which is an integral part
of this document.
In this standard Annex A is normative.
This standard is in conformity with the general requirements already established by CEN/TC 164 in the field of
water supply.
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
product covered by this standard:
this standard provides no information as to whether the product may be used without restriction in any of
the member states of the EU or EFTA;
it should be noted that, while awaiting the adoption of verifiable European criteria, existing national

1 Scope
This European Standard specifies the requirements and associated test methods applicable to ductile iron
pipes, fittings, accessories and their joints for the construction of pipelines outside buildings:
to convey water (e.g. water intended for human consumption, fire protection, snow guns, irrigation, hydro-
electric, re-used water pipelines etc.);
with or without pressure;
to be installed below or above ground.
This standard is applicable to pipes, fittings and accessories which are
manufactured with socketed, flanged or spigot ends;
supplied externally and internally coated;
suitable for fluid temperatures between 0 °C and 50 °C, excluding frost;
not intended for use in areas subject to fire regulations.
NOTE 1 This does not preclude special arrangements for the products to be used at higher temperatures.
This standard covers pipes and fittings cast by any type of foundry process or manufactured by fabrication of
cast components, as well as corresponding joints and accessories, in a size range extending from DN 40 to
DN 2000, inclusive.
This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and
standard coatings of ductile iron pipes and fittings. It also gives performance requirements for all components
including joints. Joint design and gasket shapes are outside the scope of this standard.
In addition reference is made to the performance requirements of couplings, flange adaptors and saddles
manufactured for use with ductile iron pipes and fittings.
NOTE 2 In this standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).
