This European Standard specifies performance requirements as defined in table 1 and describes test methods for precast concrete units, including joints (elastomeric, plastomeric or other sealing materials, either integrated in the unit or supplied separately), for inspection chambers designed to be used for inverts not exceeding 2 metres deep and manholes, of circular, rectangular (with or without chamfered or rounded corners) or elliptical internal shape, unreinforced, steel fibre and reinforced, with nominal sizes not exceeding DN 1250 for units with a circular bore or LN 1250 for units with a rectangular or elliptical shape.
