DIN EN 295-5:2013-05

The standards of the series EN 295 "Vitrified clay pipe systems for drains and sewers" contain requirements for vitrified clay components for buried pipe systems for drains and sewers operated for drainage of domestic waste water, surface water and rainwater generally operated as gravity pipelines. Temporarily increased pressures or permanently low positive pressures are permitted, however. If applicable, various load capacity classes, joint systems, nominal lengths and fittings as well as requirements for materials made of rubber, polyurethane, polypropylene and other components connected with vitrified clay pipes and fittings are specified. The product standards of this standard series have been prepared under a mandate for the implementation of the Construction Products Directive (89/106/EC) and contain the essential requirements, the compliance to which is necessary within the framework of CE marking for placing these products on the European market. Product standard DIN EN 295-5 contains the requirements for perforated pipes and compatible fittings made from vitrified clay with or without sockets for use in land drains and drainage of waste tips. In order to allow for the selection of the suitable product for the respective application, different strength classes and areas of perforations are specified. Pipes and fittings according to this standard can also be used for percolation into the ground. The committee responsible for this standard is NA 119-05-07 AA "Steinzeugrohre und -schächte für Abwasserkanäle und -leitungen (CEN/TC 165/WG 2)" ("Vitrified clay pipes and manholes for drains and sewers (CEN/TC 165/WG 2)") at DIN.
