EN 476:2011
(Main)General requirements for components used in drains and sewers
General requirements for components used in drains and sewers
This European Standard specifies general requirements for components inside and outside buildings (see EN 12056-1) such as pipes, fittings and manholes with their respective joints intended for use in discharge pipes, drains and sewers which operate as gravity systems allowing for a maximum pressure of 40 kPa.
It also specifies general requirements for components used in hydraulically and pneumatically pressurised discharge pipes, drains and sewers.
It provides basic specifications to be respected in material related product standards for these applications.
It is not applicable for the direct evaluation of products. It is applicable as a reference for drawing up a product specification, if there is no product standard available.
NOTE Where the term "inside buildings" is used in the context of components fixed inside buildings, it also includes discharge pipes and fittings fixed on external surfaces of buildings.
This European Standard covers components to be used in conveying in a satisfactory manner:
- domestic wastewater;
- rainwater and surface water; and
- other waste waters acceptable for discharge into the system (e.g. industrial wastewater).
This European standard applies to components of circular and other cross sections.
This European Standard applies equally to components which are factory-made and to those constructed on site, where applicable.
This European Standard does not apply to components used for trenchless construction according to EN 14457 and for components used for renovation of drains and sewers according to EN 13380.
Allgemeine Anforderungen an Bauteile für Abwasserleitungen und -kanäle
Diese Europäische Norm legt allgemeine Anforderungen an Bauteile innerhalb und außerhalb von Gebäuden (siehe EN 12056-1), wie Rohre, Formstücke und Einsteigschächte mit ihren jeweiligen Verbindungen fest, die für Abwasserleitungen und -kanäle bestimmt sind und die als Schwerkraftentwässerungssysteme (Freispiegelsystem) mit maximal 40 kPa betrieben werden. Sie legt ebenfalls allgemeine Anforderungen an Bauteile für hydraulisch und pneumatisch betriebene Abwasserdruckrohre, -leitungen und -kanäle fest. Sie enthält grundlegende Festlegungen, die für diese Anwendungen in den werkstoffbezogenen Produktnormen zu berücksichtigen sind. Sie ist nicht anwendbar zur direkten Beurteilung von Produkten. Sie ist als Referenz zur Erstellung einer Produktspezifikation anwendbar, sofern keine Produktnorm zur Verfügung steht.
ANMERKUNG Wird der Begriff „innerhalb von Gebäuden“ in Verbindung mit Bauteilen verwendet, die innerhalb des Gebäudes befestigt sind, schließt das auch an den Außenflächen der Gebäude befestigte Abwasserleitungen und Formstücke mit ein.
Diese Europäische Norm behandelt Bauteile, die in zufriedenstellender Weise eingesetzt werden, um
- häusliche Abwässer;
- Regen- und Oberflächenwasser; sowie
- weitere Abwässer (z. B. industrielles Abwasser), die zur Ableitung in das System zulässig sind, abzuleiten.
Diese Europäische Norm gilt für Bauteile mit kreisförmigem Querschnitt sowie weiteren Querschnitten. Diese Europäische Norm gilt gleichermaßen für werkseitig und, soweit zutreffend, für vor Ort hergestellte Bauteile. Diese Europäische Norm ist nicht auf Bauteile anwendbar, die bei grabenlosem Einbau nach EN 14457 verwendet werden und nicht für Bauteile, die für die Renovierung von Abwasserleitungen und -kanälen nach EN 13380 eingesetzt werden.
Exigences générales pour les composants utilisés pour les branchements et les collecteurs d'assainissement
La présente Norme européenne spécifie les exigences générales applicables aux composants à l'intérieur et
à l'extérieur des bâtiments (voir EN 12056-1), tels que les tuyaux, les raccords et les regards avec leurs
assemblages respectifs, destinés à être utilisés dans les canalisations d’évacuation, les branchements et les
collecteurs fonctionnant comme des réseaux à écoulement libre permettant d’admettre une pression
maximale de 40 kPa.
Elle spécifie également les exigences générales applicables aux composants utilisés dans les canalisations
d'évacuation, les branchements et les collecteurs fonctionnant sous pression hydraulique et pneumatique.
La présente norme fournit des spécifications de base à respecter dans les normes de produits associées aux
matériaux employés pour ces applications.
Elle n'est pas applicable à l'évaluation directe des produits, mais sert de référence pour l'élaboration d'une
spécification de produit lorsqu’aucune norme de produit n'est disponible.
NOTE L’expression « à l’intérieur des bâtiments » est employée dans le contexte des composants fixés à l’intérieur
des bâtiments et inclut également les canalisations d’évacuation et les raccords fixés aux surfaces extérieures des
bâtiments.
La présente Norme européenne traite des composants à utiliser pour transporter de manière satisfaisante :
- les eaux usées domestiques ;
- les eaux pluviales et les eaux de surface ; et
- d'autres eaux usées dont l'évacuation dans le réseau est acceptable (par exemple eaux usées
industrielles).
La présente Norme européenne s’applique aux composants de section circulaire ou non.
La présente Norme européenne s’applique de la même façon aux composants qui sont préfabriqués et aux
composants construits in situ, le cas échéant.
Splošne zahteve za elemente za odvod odpadne vode in kanalizacijo
Ta evropski standard določa splošne zahteve za elemente, kot so cevi, fitingi in vstopne odprtine z ustreznimi spoji, ki se uporabljajo pri odtočnih ceveh, vodih in kanalih (rezultat združitve EN 476, EN 773 in EN 1293).
