ISO 9924-1:2016规定了一种热重法，用于测定硫化胶和未固化化合物中的总有机物含量、炭黑含量和灰分。300°C下的质量损失是化合物挥发性物质含量的近似指南。 该方法适用于分析单独存在或作为混合物存在的含有以下橡胶的橡胶化合物和硫化胶: a） 天然或合成来源的聚异戊二烯； b） 聚丁二烯； c） 苯乙烯-丁二烯共聚物； d） 异丁烯-异戊二烯共聚物； e） 乙烯-丙烯共聚物和相关的三元共聚物。 注:该方法的应用领域可以扩展到含有不同于本款所述橡胶的化合物的分析，前提是该方法的适用性事先使用已知化合物或具有类似组成的硫化胶进行测试。ISO 9924涵盖了其他化合物2. 该方法不适用于含有聚合物的橡胶，这些聚合物在热解过程中形成碳质残留物，如许多氯- 或含氮橡胶。 该方法也不适用于含有在热解过程中导致碳质残留物形成的添加剂的材料，例如钴盐和铅盐或酚醛树脂。 该方法不适用于含有矿物填料的化合物，如碳酸盐或水合氧化铝，它们在25°C至650°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的校正。 该方法不适用于测定含有非橡胶有机成分的化合物或硫化胶的总聚合物含量，这些成分不能通过根据ISO 1407进行的溶剂萃取完全去除。

ISO 9924-1:2016 specifies a thermogravimetric method for the determination of the total organic content, carbon black content and ash in vulcanizates and uncured compounds. The loss in mass at 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 following rubbers occurring alone or as mixtures: a) polyisoprene of natural or synthetic origin; b) polybutadiene; c) styrene-butadiene copolymers; d) isobutylene-isoprene copolymers; e) ethylene-propylene copolymers and related terpolymers. NOTE The field of application of the method may be extended to 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 a similar composition. Other compounds are covered in ISO 9924？2. The method is not suitable for rubbers containing polymers which form a carbonaceous residue during pyrolysis, such as many chlorine- or nitrogen-containing rubbers. The method is also not suitable for materials containing additives which cause the formation of carbonaceous residues during pyrolysis, such as cobalt and lead salts or phenolic resins. 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 650 °C, unless suitable corrections based on prior knowledge of filler behaviour can be made. The method is not suitable for the determination of the total polymer content of compounds or vulcanizates containing non-rubber organic ingredients that cannot be completely removed by solvent extraction carried out in accordance with ISO 1407.
