General requirements for components used in drains and sewers
This document specifies general requirements to be respected in product standards for components such as pipes, fittings, inspection chambers and manholes with their respective joints intended for use in drains and sewers inside and outside buildings 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 pressurized pipes, drains and sewers.
NOTE 1 Where the term “inside buildings” is used in the context of components fixed inside buildings, it also includes pipes and fittings fixed on external surfaces of buildings.
NOTE 2 This document is not a product standard and therefore not intended for the direct evaluation of products.
This document covers components to be used in conveying in a satisfactory manner:
— domestic wastewater;
— rainwater and surface water;
— other wastewater acceptable for discharge into the system.
This document is applicable to components of circular and other cross sections.
This document is equally applicable to components which are factory-made and to those constructed on site, where applicable.
NOTE 3 This document 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.
This document does not supersede the functional requirements of a complete system as defined in EN 752.
Allgemeine Anforderungen an Bauteile für Abwasserleitungen und -kanäle
Dieses Dokument legt allgemeine Anforderungen fest, die in Produktnormen für Bauteile wie Rohre, Formstücke, Kontroll- und Einsteigschächte mit ihren jeweiligen Verbindungen, die für Abwasserleitungen und kanäle innerhalb und außerhalb von Gebäuden bestimmt sind und die als Schwerkraftsysteme mit höchstens 40 kPa betrieben werden, Beachtung finden müssen.
Außerdem legt es allgemeine Anforderungen an Bauteile für hydraulisch und pneumatisch betriebene Druckrohre, Abwasserleitungen und kanäle fest.
ANMERKUNG 1 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 Rohre und Formstücke mit ein.
ANMERKUNG 2 Dieses Dokument ist keine Produktnorm und daher nicht für die direkte Beurteilung von Produkten bestimmt.
Dieses Dokument behandelt Bauteile, die in zufriedenstellender Weise eingesetzt werden, um Folgendes abzuleiten:
— häusliche Abwässer;
— Regen- und Oberflächenwasser sowie
— weitere Abwässer, die zur Ableitung in das System zulässig sind.
Dieses Dokument ist auf Bauteile mit kreisförmigem Querschnitt sowie weiteren Querschnitten anzuwenden.
Dieses Dokument ist gleichermaßen auf werkseitig und, soweit zutreffend, auf vor Ort hergestellte Bauteile anzuwenden.
ANMERKUNG 3 Dieses Dokument ist nicht auf Bauteile anzuwenden, 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.
Dieses Dokument ersetzt nicht die funktionellen Anforderungen an ein komplettes System wie in EN 752 festgelegt.
Exigences générales pour les composants utilisés pour les branchements et les collecteurs d’assainissement
Le présent document spécifie les exigences générales à respecter dans les normes de produits pour les composants tels que les tuyaux, les raccords, les boîtes de branchement ou d’inspection et les regards de visite avec leurs assemblages respectifs, destinés à être utilisés dans les branchements et les collecteurs à l’intérieur et à l’extérieur des bâtiments fonctionnant comme des réseaux à écoulement libre permettant d’admettre une pression maximale de 40 kPa.
Il spécifie également les exigences générales applicables aux composants utilisés dans les tuyaux, les branchements et les collecteurs fonctionnant sous pression hydraulique et pneumatique.
NOTE 1 L’expression « à l’intérieur des bâtiments » est employée dans le contexte des composants fixés à l’intérieur des bâtiments et inclut également les tuyaux et les raccords fixés aux surfaces extérieures des bâtiments.
NOTE 2 Le présent document n’est pas une norme de produit et n’est donc pas destiné à l’évaluation directe des produits.
Le présent document 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.
Le présent document est applicable aux composants de section circulaire ou non.
Il peut s’appliquer de la même façon aux composants qui sont préfabriqués et aux composants construits in situ, le cas échéant.
NOTE 3 Le présent document ne s’applique ni aux composants utilisés pour la construction sans tranchée selon l’EN 14457, ni aux composants utilisés pour la rénovation des branchements et des collecteurs d’assainissement selon l’EN 13380.
Le présent document ne remplace pas les exigences fonctionnelles d’un système complet telles que définies dans l’EN 752.
Splošne zahteve za elemente za odvod odpadne vode in kanalizacijo
Ta dokument določa splošne zahteve, ki jih je treba upoštevati v standardih za elemente, kot so cevi, fitingi, revizijske komore in jaški z ustreznimi spoji, namenjene za uporabo v odtokih in kanalizaciji znotraj ter zunaj stavb, ki delujejo kot gravitacijski sistemi in omogočajo največji tlak 40 kPa.
Določa tudi splošne zahteve za elemente hidravličnih in tlačnih cevovodov za odvod odpadne vode ter kanalizacijo.
OPOMBA 1: Kadar se izraz »znotraj stavb« uporablja v kontekstu elementov v stavbah, vključuje tudi odvodne cevi in armature, nameščene na zunanjih površinah stavb.
OPOMBA 2: Ta dokument ni standard za izdelke in zato ni namenjen neposrednemu vrednotenju izdelkov.
Dokument zajema elemente, potrebne za odvajanje vode na zadovoljiv način, in sicer:
– odpadne vode iz gospodinjstev;
– deževnice in površinske vode; ter
– druge odpadne vode, primerne za odvajanje v sistem (npr. industrijske odpadne vode).
Dokument se uporablja za elemente krožnih in drugih prerezov.
Ta dokument se uporablja tako za tovarniško izdelane elemente kot za tiste, ki so izdelani na mestu uporabe, kjer je primerno.
OPOMBA 3: Dokument se ne uporablja za elemente, ki se uporabljajo za kanale brez izkopa v skladu s standardom EN 14457 in za elemente, ki se uporabljajo za obnovo odtokov in kanalizacije v skladu s standardom EN 13380.
Ta dokument ne nadomešča funkcionalnih zahtev celotnega sistema, kot je opredeljeno v standardu EN 752.

European foreword
This document (EN 476:2022) has been prepared by Technical Committee CEN/TC 165 “Waste water
engineering”, the secretariat of which is held by DIN.
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 October 2022, and conflicting national standards shall
be withdrawn at the latest by October 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 476:2011.
The specifications of this document are based on the requirements for wastewater systems specified in
EN 752 and EN 12056 (all parts). Significant technical differences between this edition and EN 476:2011
are as follows:
a) the Scope is clarified in the way that this document contains requirements for product standards;
b) Table 1 (Preferred nominal sizes DN/ID) and Table 2 (Preferred nominal sizes DN/OD), paragraph
5.2.1, are moved to the new Annex A;
c) the paragraphs under 5.3, Dimensions of manholes and inspection chambers, are completely
rewritten, with minimum internal dimension for different cross sections (always in compliance with
the national regulations in force at the place of installation);
d) for reaction to fire, a new 6.16 is added.
This document provides a framework for the development of product standards to be used in drain and
sewer systems inside and outside buildings. In Figure 1 the position of this document related to other
standards on this subject is given.
This document describes the general requirements to be taken into account in product standards.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia,
