DIN EN 1916:2003-04

This European Standard specifies performance requirements as defined in Table 1 and describes test methods for precast concrete pipes and fittings, unreinforced, steel fibre and reinforced, for use in pipelines with flexible joints (with seals either integrated in the units or supplied separately) and nominal sizes not exceeding DN 1750 for units with a circular bore or WN/HN 1200/1800 for units with an egg-shaped bore, for which the main intended use is the conveyance of sewage, rainwater and surface water under gravity or occasionally at low head of pressure, in pipelines that are generally buried.
