建立套筒的分类（环形密封套筒和溶剂水泥套筒）和命名系统（S、M、L和CS型），并规定设计公式和衍生尺寸以及公差，用于建筑物内排水系统的ABS管道接头和整体式接头的插座和插口，此类接头用于容纳膨胀和收缩。

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.
