Plastics pipes and fittings — Dimensions of sockets and spigots for discharge systems inside buildings — Part 4: Acrylonitrile/butadiene/styrene (ABS)

Establishes a classification (ring-seal sockets and solvent cement sockets) and designation system (types S, M, L, and CS) for sockets and specifies the design formulae and the derived dimensions, together with tolerances, of these sockets and of spigots for joints and for integral sockets of ABS pipes intended for use in discharge systems inside buildings where such joints are intended to accommodate expansion and contraction.
