本文件规定了一种热重法，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。它建立了测试材料的“指纹”。然而，结果并不总是完全对应于橡胶的理论公式。该方法适用于生胶或混炼胶，硫化和未硫化，有或没有提取。该方法适用于具有烃骨架的橡胶（NR、BR、SBR、IIR、EPDM、ACM、AEM等）。）单独使用或作为混合物使用。对于混合物，聚合物含量对应于总橡胶，并且通常不可能识别单个聚合物。本方法适用于含卤代烃主链（CR、CSM、FKM、CM、CO、ECO等）或含氮（NBR、HNBR、NBR/PVC等）的橡胶。)，以及它们的混合物。然而，这些橡胶经常形成干扰分析的含碳残留物。应用适当的程序可以最大限度地减少这些干扰。该方法也适用于具有聚硅氧烷主链的橡胶(VMQ等)和以上未列出的橡胶。

This document 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 unvulcanised, with or without 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.
