BS ISO 9924-2:2016规定了一种热重分析法，用于测定总重量 硫化胶和未硫化胶中的有机物含量、炭黑含量、含碳残留物和灰分 含有聚合物的化合物，在热解时形成含碳残留物。损失 300°C左右的质量是化合物挥发物含量的近似指南。该方法适用于分析含有 ISO 9924-1涵盖的碳氢化合物聚合物加上以下带有极性基团的共聚物 热解时形成含碳残留物:丙烯腈-丁二烯共聚物（NBR）；羧基化丙烯腈-丁二烯共聚物（XNBR）；氢化丙烯腈-丁二烯共聚物（HNBR）；氯化异丁烯-异戊二烯共聚物；溴化异丁烯-异戊二烯共聚物（BIIRs）。注1:该方法的应用范围可扩展至包括化合物分析 含有不同于本款规定的橡胶，前提是该方法的适用性 事先使用已知化合物或具有类似成分的硫化胶进行测试。注2:该方法不适用于含有矿物填料的化合物，如碳酸盐或水合物 氧化铝，其在25°C至800°C的温度范围内分解，除非可以根据填料行为的先验知识进行适当修正。注3:该方法不适用于测定化合物的总聚合物含量 含有不能通过溶剂萃取完全去除的非橡胶有机成分 根据ISO 1407。交叉引用:ISO 1407购买本文件时提供的所有现行修订均包含在购买本文件中。

BS 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. 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:acrylonitrile-butadiene copolymers (NBRs);carboxylated acrylonitrile-butadiene copolymers (XNBRs);hydrogenated acrylonitrile-butadiene copolymers (HNBRs);chlorinated isobutylene-isoprene copolymers (CIIRs);brominated isobutylene-isoprene copolymers (BIIRs).NOTE 1 The field of application of the method may be extended to include the analysis of compounds containing rubbers different from those given in this subclause, provided that the applicability of the method is tested beforehand using known compounds or vulcanizates having similar composition.NOTE 2 The method is not suitable for compounds containing mineral fillers, such as carbonates or hydrated aluminium oxides, which decompose in the temperature range from 25 °C to 800 °C, unless suitable corrections based on prior knowledge of filler behaviour can be made.NOTE 3 The method is not suitable for the determination of the total polymer content of compounds containing non-rubber organic ingredients that cannot be completely removed by solvent extraction carried out in accordance with ISO 1407.Cross References:ISO 1407All current amendments available at time of purchase are included with the purchase of this document.
