This International Standard specifies: physical and chemical tests on raw rubbers; standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics of emulsion- and solution-polymerized styrene-butadiene rubbers (SBR), including oil-extended rubbers. It applies to those rubbers listed in Table1 which are normally used in vulcanized form. Table1Types of raw styrene-butadiene rubber Rubber
