Thermoplastic pipes. Resistance to liquid chemicals. Classification - Unplasticized poly(vinyl chloride) (PVC-U), high-impact poly(vinyl chloride) (PVC-HI) and chlorinated poly(vinyl chloride) (PVC-C) pipes Ingestion-build-67170 instrumentation1 Scope The method of classification given in this part of ISO 4433 serves to determine the chemical resistance of unplasticized poly(vinyl chloride) (PVC U), high impact poly(vinyl chloride) (PVC HI) and chlorinated poly(vinyl chloride) (PVC C) pipes designed for the conveyance of liquids in the absence of pressure and stress (e. g. due to earth loads or traffic loads, dynamic or internal stresses). To determine the chemical resistance, the method
