This European Standard specifies general requirements for components such as pipes, fittings and manholes with their respective joints intended for use in discharge pipes, drains and sewers which operate as gravity systems where any pressure likely to occur is a maximum of 40 kPa. It also specifies general requirements for components used in hydraulically and pneumatically pressurized discharge pipes, drains and sewers and provides basic specifications and minimum requirements to be respected in all product standards for this application. 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 waste water; rainwater and surface water; and, other waste waters (e. g. industrial waste water) that will not damage the components. 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 for components used for trenchless construction according to EN 14457 and for components used for renovation of drains and sewers according to EN 13380.
