This prt is pplicble to pipes nd fittings with smooth internl nd profiled externl surfces, designted s Type B. It specifies test methods nd test prmeters s well s requirements. This prt is pplicble to: ) structured-wll pipes nd fittings, which re intended to be used buried underground outside the building structure, reflected in the mrking of products by U ; b) structured-wll pipes nd fittings, which re intended to be used buried underground both outside (ppliction re code U ) nd within the building structure (ppliction re code D ), reflected in the mrking of products by UD. This prt is pplicble to structured-wll pipes nd fittings with or without n integrl socket with elstomeric ring sel joints s well s welded nd fused joints. This prt covers rnge of pipe nd fitting sizes, mterils, pipe constructions, stiffness clsses, ppliction clsses, nd tolernce clsses nd gives recommendtions concerning colours. NOTE 1 It is the responsibility of the purchser or specifier to mke the pproprite selections from these spects, tking into ccount their prticulr requirements nd ny relevnt ntionl regultions nd instlltion prctices or codes.
