General requirements for components used in drains and sewers Ingestion-build-251241 establishes requirements for safety lifecycle1 Scope This European Standard specifies general requirements for components inside and outside buildings (see EN 120561) 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
