Scope: This document 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 (SBRs), including oil-extended rubbers. It applies to those rubbers listed in Table 1 which are normally used in vulcanized form. Table 1 — Types of raw styrene-butadiene rubber Rubber (oil-extended or non-oil-extended) Styrene Type of copolymer Total content % mass fraction Block content % mass fraction Series A Emulsion SBR Solution SBR Solution SBR Random Random Partial block ≤50 ≤50 ≤5000 ≤30 Series B Emulsion SBR Solution SBR Solution SBR Random Random Partial block >50 >50 ≤5000 >30
