本文件提供了一种定性方法，用于使用串联气相色谱/质谱法通过橡胶的热解产物识别橡胶。 该方法适用于未加工状态的橡胶以及未硫化和硫化化合物。化合物可以基于单一橡胶或两种或两种以上橡胶的混合物。混合物中特定橡胶的含量为<；10%，检测和识别可能很困难。 第4条给出了橡胶的非限制性清单。

This document provides a qualitative method for the identification of rubbers by their pyrolysis products using tandem gas-chromatography/mass spectrometry. The method applies to rubbers in the raw state and to unvulcanized and vulcanized compounds. Compounds can be based on a single rubber or a blend of two or more rubbers. Where the level of a particular rubber in a blend is <10 %, detection and identification can be difficult. A non-restrictive list of rubbers is given in Clause 4.
