Scope
ISO 9924-2:2016 specifies a thermogravimetric method for the determination of the total organic content, carbon black content, carbonaceous residue and ash in vulcanizates and uncured compounds containing polymers which form a carbonaceous residue on pyrolysis (see 1.2). The loss in mass at around 300 °C is an approximate guide to the volatile-matter content of the compound.


The method is suitable for the analysis of rubber compounds and vulcanizates containing the hydrocarbon polymers covered by ISO 9924‑1 plus the following copolymers with polar groups which form a carbonaceous residue on pyrolysis:


a) acrylonitrile-butadiene copolymers (NBRs);


b) carboxylated acrylonitrile-butadiene copolymers (XNBRs);


c) hydrogenated acrylonitrile-butadiene copolymers (HNBRs);


d) chlorinated isobutylene-isoprene copolymers (CIIRs);


e) brominated isobutylene-isoprene copolymers (BIIRs).
