Chemical tests for raw and vulcanized rubber. Methods for determination of polymer content - Polyisoprene content Ingestion-build-52208 PD CEN/TR 15371 discusses theWhat is BS 7164 7. 1 Methods of determination of polymer content about? BS 7164 is a series on chemical tests for raw and vulcanized rubber. Raw and vulcanized rubber is any type of rubber that's been hardened through the use of heat and sulfur. BS 7164 7. 1 specifies a method for the determination of polyisoprene occurring as natural isoprene rubber (NR)2), synthetic isoprene rubber (IR), balata and gutta percha, in the total solids from NR or IR
