标准摘要
[中文适用范围]： 本文件规定了通过热解-气相色谱图（pyrograms）对生橡胶、未硫化或半硫化化合物中的聚合物或聚合物混合物进行定性识别的方法。此方法允许单一种类橡胶或混合物的定性识别，特殊情况除外。本文件不用于定量分析。该方法主要适用于单一聚合物。当热解图显示特征烃时，也可适用于混合物。详见第5章。在经验证的情况下，该方法还可适用于其他类型的聚合物。 [外文原描述]： This document specifies a method for the identification of polymers, or blends of polymers, in raw rubbers and in vulcanized or unvulcanized compounds from pyrograms (pyrolysis-gas chromatographic patterns) obtained under the same conditions. This allows qualitative identification of single rubbers or blends, with exceptions discussed below. This document is not intended for quantitative analysis. The method applies first and foremost to single polymers. When the pyrogram indicates a characteristic hydrocarbon, the method is also applicable to blends. For details, see Clause 5. The method can be also applicable to other types of polymer when verified by the analyst in each particular case. NOTE The use of this document pre-supposes sufficient working knowledge of the principles and techniques of gas chromatography to enable the analyst to carry out the operations described and to interpret the results correctly.
