Ductile iron wide tolerance couplings and flange adaptors for use with pipes of different materials: ductile iron, Grey iron, Steel, PVC-U PE, Fibre-cement

This document specifies the requirements and associated test methods applicable to wide tolerance ductile iron couplings and wide tolerance flange adaptors intended for use with pipe components made from a number of pipe materials (ductile iron, grey iron, PE, PVC-U, steel, fibre-cement), for providing a leak tight seal over a wide range of pipe external diameters :
-   to convey water (e.g. potable water) ;
-   with or without pressure ;
-   to be installed below or above ground, inside or outside buildings.
This standard is not intended to cover sewerage or gas applications, where other requirements may be necessary.
This standard specifies requirements for materials, dimensions and tolerances, mechanical properties and standard coatings of ductile iron products.
This standard covers ductile iron products cast by any type of foundry process or manufactured by fabrication of cast components, as well as corresponding joints, in a size range extending from DN 40 to DN 600, for an allowable operating pressure (PFA) up to 16 bar, for fluid temperatures between 0 °C and 25 °C excluding frost. For higher temperatures, up to 50 °C, additional type testing should be carried out.
It also gives performance requirements and associated test methods for restrained and non-restrained flexible joints. Joint design and gasket shapes are outside the scope of this standard.
NOTE 1   PFA may be limited depending on pipe materials effectively connected.
NOTE 2   In this standard, all pressures are relative gauge pressures, expressed in bars (100 kPa = 1 bar).
NOTE 3   EN 545 gives the specifications for the ductile iron fittings to be used with ductile iron pipes.
NOTE 4   EN 12842 gives the specifications for the ductile iron fittings to be used with PVC-U and PE pipes.

Großbereichskupplungen und -flanschadapter aus duktilem Gusseisen zur Verbindung von Rohren aus unterschiedlichen Werkstoffen: Duktiles Gusseisen, Grauguss, Stahl, PVC-U, PE, Faserzement

La présente norme européenne prescrit les exigences et les méthodes d'essais associées, applicables aux manchons à larges tolérances et aux adaptateurs de brides à larges tolérances destinés à être utilisés avec des composants de canalisation faits d'un certain nombre de matériaux de canalisation (fonte ductile, fonte grise, PE, PVC-U, acier, fibres-ciment), afin d'assurer un assemblage étanche sur une large plage de diamètres extérieurs de tuyaux :
¾   pour transporter de l'eau (par exemple de l'eau potable) ;
¾   avec ou sans pression ;
¾   pour être installés dans le sol ou en aérien, à l'intérieur ou à l'extérieur des bâtiments.
Cette norme ne couvre pas les applications assainissement ou gaz, où des prescriptions supplémentaires peuvent être nécessaires.
Cette norme prescrit les exigences pour les matériaux, les dimensions et tolérances, les propriétés mécaniques et les revêtements habituels des raccords en fonte ductile.
Cette norme traite des raccords coulés par tout procédé de fonderie ou fabriqués à partir de composants moulés, ainsi que les assemblages correspondants, pour la gamme des DN 40 à DN 600, pour des pressions de fonctionnement admissibles (PFA) pouvant atteindre 16 bar, pour des températures de fluide comprises entre 0 °C et 25 °C, gel exclu. Pour des températures supérieures, jusqu'à 50 °C, des essais de performance supplémentaires devraient être réalisés.
Elle donne également les prescriptions de performance et les méthodes d'essai associées pour les assemblages flexibles verrouillés ou non. La conception des assemblages et la forme des bagues de joints sont en-dehors du domaine d'application de cette norme.
NOTE 1   Selon le matériau de canalisation effectivement assemblée, la PFA peut être réduite.
NOTE 2   Dans cette norme, toutes les pressions sont des pressions relatives, exprimées en bars (100 kPa = 1 bar).

Adaptateurs de brides et manchons à larges tolérances en fonte ductile destinés à être utilisés avec des tuyaux faits de différents matériaux : fonte ductile, fonte grise, acier, PVC-U, PE, fibre-ciment

Spojke in prirobnične prilagoditve široke uporabe za cevi iz različnih materialov: duktilne litine, sive litine (z lamelastim grafitom), jekla, PVC-U, PE, vlaknatega cementa
