General requirements for components used in drains and sewers; German version EN 476:2011
Allgemeine Anforderungen an Bauteile für Abwasserleitungen und -kanäle; Deutsche Fassung EN 476:2011
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 drains and sewers which operate as gravity (sewer) systems allowing for a maximum pressure of 40 kPa. It also specifies general requirements for components used in hydraulically and pneumatically pressurized discharge pipes, drains and sewers. It contains 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. 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 (for instance 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. The Committee responsible for this standard is NA 119-05-09 AA "Allgemeine Anforderungen an Rohre, Rohrverbindungen etc. für Abwasserkanäle und -leitungen (CEN/TC 165/WG 1 und CEN/TC 165/WG 1/TG 1)" ("General requirements for pipes, pipe connections, etc. used in drains and sewers (CEN/TC 165/WG 1 and CEN/TC 165/WG 1/TG 1)") at DIN.
