标准范围
ISO/TS 20593:2017规定了测定环境颗粒物(PM)样品中轮胎和道路磨损颗粒(TRWP)的空气浓度(μ g/m3)、质量浓度(μ g/g)和质量分数(%)的方法。ISO/TS 20593:2017确立了空气样品采集、从样品中生成热解碎片以及对生成的聚合物碎片进行定量的原则。定量的聚合物质量用于计算轮胎胎面在PM中的分数和轮胎胎面在空气中的浓度。这些量以TRWP为基础表示，TRWP包括轮胎胎面的质量和道路磨损结壳的质量，也可以以轮胎橡胶聚合物或轮胎胎面为基础表示。空气样本收集在石英纤维过滤器上，具有PM2、5或PM10范围内的尺寸选择性输入。该方法适用于室内或室外大气中TRWP的测定。
ISO/TS 20593:2017 specifies a method for the determination of the airborne concentration (μg/m3), mass concentration (μg/g) and mass fraction (%) of tyre and road wear particles (TRWP) in ambient particulate matter (PM) samples.ISO/TS 20593:2017 establishes principles for air sample collection, the generation of pyrolysis fragments from the sample, and the quantification of the generated polymer fragments. The quantified polymer mass is used to calculate the fraction of tyre tread in PM and concentration of tyre tread in air. These quantities are expressed on a TRWP basis, which includes the mass of tyre tread and mass of road wear encrustations, and can also be expressed on a tyre rubber polymer or tyre tread basis.Air sample collection is on quartz fibre filters with size-selective input in a range of PM2,5 or PM10. The method is suitable for the determination of TRWP in indoor or outdoor atmospheres.
