This document specifies methods for the determination of chlorine and/or bromine present in raw rubber as well as vulcanized or unvulcanized rubber compounds. 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.
Abstract
Overview
ISO 7725:2020 - Rubber and rubber products - Determination of chlorine and bromine content - specifies laboratory methods to quantify in raw, vulcanized and unvulcanized rubber. The standard covers natural rubber and common synthetic rubbers (isoprene, SBR, BR, butyl and halogenated butyl, nitrile, EPDM, chloroprene and epichlorohydrin). It defines sample-preparation routes and two analytical approaches: and .
