This standard is included in DIN Handbook 88, 13-4, 13-5, 152 and 259. Applies to trenchless construction and testing of new drains and sewers in the ground, operating as gravity pipelines, formed using prefabricated pipes and their joints. Trenchless construction and testing of drains and sewers operating under pressure is also covered together with prEN 805. Also applicable to trenchless replacement techniques, but does not apply to renovation techniques for existing drains and sewers.
