Scope

GB/T 33608-2017 is the English-translated version of 建筑排水用硬聚氯乙烯（PVC-U）结构壁管材.

GB/T 33608-2017 covers the unplasticized poly(vinyl chloride) (PVC-U) structured-wall pipe used for soil and waste discharge inside buildings, extruded from PVC resin with the necessary additives; foamed pipe is outside its scope.

It gives the terms and definitions, the materials, the classification, the structure and marking, the requirements, the test methods, the inspection rules and the marking, transport and storage of the pipe.

It defines the helical rib that runs along the inner wall and the height of that rib. For the tests it cites the methods for density, the standard conditioning environment, longitudinal shrinkage, Vicat softening temperature, tensile properties, dimensions, ring stiffness, external impact resistance and the curvature of rigid pipe. It was issued on 12 May 2017 and has applied since 1 December 2017.
