标准范围

ISO 10640:2011提供了一种评估聚合物系统在实验室加速风化以及户外暴露期间老化的方法。这种方法主要适用于光老化，但也适用于热老化。该方法确定了在光老化过程中控制材料物理性能劣化的化学变化之后的分析。主要程序基于红外光谱分析，并在标准中进行了描述。此外，紫外光谱用于监测某些添加剂的行为，并确定聚合物材料变色的来源（色素和着色剂的降解，或聚合物变黄）。附录中给出了该方法的应用示例，作为解释结果的指南。

ISO 10640:2011 provides a methodology to assess the ageing of polymeric systems during exposure to laboratory accelerated weathering as well as in outdoor exposures. This methodology applies mainly to photoageing, but it can also be applied to thermal ageing.The methodology identifies analyses that follow the chemical changes which control the deterioration of physical properties of materials during photoageing. The main procedure is based on IR spectroscopy analysis and is described in the standard. In addition, UV spectroscopy is used for monitoring the behaviour of some additives and to identify the origin of discoloration in polymeric materials (degradation of pigments and colorants, or polymer yellowing).Examples of applications of this methodology are given in an annex as guidance for the interpretation of the results.
