ISO 9924-3:2009规定了一种热重分析法，用于测定橡胶化合物的主要成分，如弹性体、炭黑和矿物填料。它建立了被测材料的“指纹”。然而，结果并不总是完全符合橡胶的理论公式。本方法适用于初步提取后硫化和未硫化的生胶或复合橡胶。该方法适用于含有碳氢主链（NR、BR、SBR、IIR、EPDM、ACM、AEM等）的橡胶，单独使用或作为混合物使用。对于混合物，聚合物含量相当于橡胶总量，通常无法识别单个聚合物。本方法适用于含卤代烃主链（CR、CSM、FKM、CM、CO、ECO等）或含氮橡胶（NBR、HNBR、NBR/PVC等）及其混合物。然而，这些橡胶通常会形成干扰分析的含碳残留物。应用适当的程序将这些干扰降至最低。该方法也适用于具有聚硅氧烷主链（VMQ等）的橡胶和上述未列出的橡胶。

ISO 9924-3:2009 specifies a thermogravimetric method for the determination of the main constituents of rubber compounds such as elastomer(s), carbon black and mineral filler.It establishes the “fingerprint” of the tested material. However, the result does not always correspond exactly to the theoretical formula of the rubber.This method applies to raw or compounded rubbers, vulcanized and unvulcanized, after preliminary extraction.This method applies to rubbers with hydrocarbon backbones (NR, BR, SBR, IIR, EPDM, ACM, AEM, etc.) used alone or as mixtures. For the mixtures, the polymer content corresponds to the total rubber, and it is not usually possible to identify individual polymers.This method applies to rubbers with halogenated hydrocarbon backbones (CR, CSM, FKM, CM, CO, ECO, etc.) or containing nitrogen (NBR, HNBR, NBR/PVC, etc.), as well as to their mixtures. However, these rubbers often form carbonaceous residues which interfere with the analysis. Application of an appropriate procedure minimizes these interferences.This method also applies to rubbers with a polysiloxane backbone (VMQ, etc.) and to rubbers not listed above.
