This document specifies methods for the determination of chlorine and\/or bromine present in raw rubber as well as vulcanized or unvulcanized rubber compounds.<\/p>\n

The methods are applicable to natural rubbers and to the following synthetic rubbers: isoprene, styrene-butadiene, butadiene, butyl, halogenated butyl, nitrile, ethylene-propylene, chloroprene and epichlorohydrin.<\/p>\n
