标准摘要
[中文适用范围]： 本部分规定了用于测定硫化橡胶和未硫化的橡胶化合物中总有机物含量、炭黑含量、碳残留物和灰分的热重分析方法。该方法适用于含有在热解时形成碳残留物的聚合物的橡胶化合物和硫化橡胶。 此方法适合分析包含ISO 9924-1所述聚合物以及以下具有极性基团且热解时形成碳残留物的共聚物的橡胶化合物和硫化橡胶：a)丙烯腈丁二烯共聚物（NBRs）；c)氢化丙烯腈丁二烯共聚物（HNBRs）；e)溴化异丁ylene-异戊二烯共聚物。 [外文原描述]： 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).
