塑料管材和管件 建筑物内排水系统的承口和插口尺寸 第4部分:丙烯腈/丁二烯/苯乙烯(ABS)

[中文适用范围]： 建立了插座的分类（环形密封插座和溶剂水泥插座）和命名系统（S、M、L 和 CS 型），并规定了这些插座和插口的设计公式和衍生尺寸以及公差接头和 ABS 管道的整体承插口，用于建筑物内的排放系统，此类接头旨在适应膨胀和收缩。 [外文原描述]： 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.
