标准范围

ISO 7270-1:2003规定了从相同条件下获得的热解图（热解气相色谱图）中识别未加工橡胶和硫化或未硫化化合物中的聚合物或聚合物混合物的方法。这允许对单一橡胶或混合橡胶进行定性识别，以下讨论的例外情况除外。ISO 7270的本部分不用于定量分析。该方法首先适用于单一聚合物。当热解图显示特征碳氢化合物时，该方法也适用于混合物。该方法可能也适用于其他类型的聚合物，但这必须由分析员在每个特定情况下进行验证。

ISO 7270-1:2003 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 part of ISO 7270 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. The method may be also applicable to other types of polymer, but this must be verified by the analyst in each particular case.
