标准范围

ISO/TS 21396:2017规定了一种测定环境样品中轮胎和道路磨损颗粒（TRWP）的土壤或沉积物质量浓度（μg/g）的方法。ISO/TS 21396:2017确立了土壤或沉积物样品采集、样品热解碎片生成以及生成聚合物碎片量化的原则。定量聚合物质量用于计算土壤或沉积物中TRWP的浓度。这些数量以TRWP为基础表示，包括轮胎胎面质量和道路磨损结垢质量，也可以以轮胎橡胶聚合物或轮胎胎面为基础表示。注:轮胎和路面磨损颗粒是指在轮胎使用寿命期间，在轮胎和路面之间的摩擦界面处产生的细长颗粒的离散质量。这些颗粒由富含道路表面矿物结壳的轮胎胎面组成。

ISO/TS 21396:2017 specifies a method for the determination of the soil or sediment mass concentration (μg/g) of tyre and road wear particles (TRWP) in environmental samples.ISO/TS 21396:2017 establishes principles for soil or sediment 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 concentration of TRWP in soil or sediment. 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.NOTE Tyre and road wear particles are a discrete mass of elongated particles generated at the frictional interface between the tyre and roadway surface during the service life of a tyre. The particles consist of tyre tread enriched with mineral encrustations from the roadway surface.
