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 outside buildings:
- to convey different types of water (e.g. raw water, treated water, re-used water) for all types of applications (e.g. water intended for human consumption, for fire protection, for snow making, for irrigation, for hydro-electricity etc.);
- with or without pressure;
- to be installed below or above ground.
This European 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 European 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 2 000, inclusive.
This European 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 European 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 verschiedener Arten von Wasser (z. B. Rohwasser, behandeltes Wasser, wieder
aufbereitetes Wasser) für alle Anwendungsarten (z. B. Wasser für den menschlichen Gebrauch, für die
Brandbekämpfung, für die Schneeherstellung, für die Bewässerung, für Wasserkraftanlagen usw.);
⎯ mit oder ohne Innendruck;
⎯ oberirdisch oder erdverlegt.
Diese Europäische 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 Frostbereiches, und 50 °C
geeignet sind;
⎯ nicht für die Anwendung in Bereichen, die Bestimmungen zum Brandverhalten unterliegen, vorgesehen
sind.
Dies schließt besondere Vereinbarungen für die Verwendung dieser Produkte bei höheren Temperaturen
nicht aus.
Diese Europäische 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 Nennweitenbereich von DN 40 bis einschließlich DN 2 000.
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 Anwendungsbereiches
dieser Europäischen Norm.
Darüber hinaus wird auf die Mindestleistungsanforderungen an Kupplungen, Flanschadapter und Sattelstücke,
die für den Gebrauch mit Rohren und Formstücken aus duktilem Gusseisen hergestellt sind, Bezug
genommen.
ANMERKUNG In dieser Europäischen Norm sind alle Drücke relative Drücke und werden in bar angegeben
(100 kPa = 1 bar).
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 prescriptions 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 à l'extérieur de bâtiments :
⎯ pour transporter différents types d'eau (par exemple l'eau potable, l'eau traitée ou l'eau réutilisée)
destinés à tous les types d'applications (par exemple l'eau destinée à la consommation humaine, à la
protection contre les incendies, à la fabrication de neige, à l'irrigation, à l'hydroélectricité, etc.) ;
⎯ avec ou sans pression ;
⎯ installées dans le sol ou en aérien.
La présente Norme européenne est applicable aux tuyaux, raccords et accessoires qui sont :
⎯ fabriqués avec des extrémités à emboîture, à bride ou à bout uni ;
⎯ livrés revêtus extérieurement et intérieurement ;
⎯ utilisables pour des températures de fluide allant de 0 °C à 50 °C, gel exclus ;
⎯ non destinés à l'usage dans des domaines soumis une réglementation sur les risques d'incendie.
Ceci n'exclut pas les dispositions spéciales permettant d'utiliser les produits à des températures plus élevées.
La présente Norme européenne 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 2 000 inclus.
La présente Norme européenne spécifie les prescriptions pour les matériaux, les dimensions et tolérances,
les propriétés mécaniques et les revêtements de base 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 garnitures de joint ne font pas partie du domaine
d'application de cette norme.
Cevi, fitingi, pribor in spoji iz nodularne litine za vodovodno omrežje - Zahteve in preskusne metode
Ta evropski standard opredeljuje zahteve in pridružene preskusne metode, ki veljajo za cevi, fitinge, pribor in spoje iz nodularne litine za gradnjo cevovodov zunaj stavb: - za zajem različnih vrst vode (npr. neobdelana vode, obdelana voda, ponovno uporabljena voda) za vse vrste uporab (npr. voda, ki jo uporabljajo ljudje, za zaščito pred ognjem, za izdelavo snega, za namakanje in za hidroelektriko); - z ali brez tlaka; - za vgradnjo pod ali nad zemljo. Ta standard velja za cevi, fitinge in pribor, kot sledi: - proizvedene z vtičnimi ali spojnimi konci ali zatiči; dobavljene z zunanjo ali notranjo prevleko; primerne za temperature tekočine med 0 °C in 50 °C, kar izključuje zmrzal; - niso namenjeni za uporabo na področjih, ki so predmet požarnih predpisov. Ta standard zajema cevi in fitinge, lite s pomočjo katere koli vrste livarskega postopka ali proizvedene z izdelavo litih komponent, kot tudi njihove spoje in pribor, v razponu velikosti med in vključno DN 40 do in vključno DN 2000. Ta standard opredeljuje zahteve za materiale, dimenzije in odstopanja, mehanske lastnosti in standardne prevleke cevi in fitingov iz nodularne litine. Prav tako podaja zahteve za delovanje za vse komponente, vključno s spoji. Zasnova spojev in oblike tesnil so zunaj področja uporabe tega standarda. Dodatno se sklicuje na zahteve za delovanje priključkov, prirobničnih adapterjev in nosilcev, proizvedenih za uporabo s pipami in fitingi iz nodularne litine.
