本文件为评估轮胎胎面化学添加剂在固化聚合物和轮胎及道路磨损颗粒（TRWP）中在整个轮胎生命周期中的环境命运建立了一般框架和考虑因素。本文件适用于实验室从已知成分的固化胎面聚合物中生成的TRWP。描述了在轮胎生命周期内可能发生的以下过程中评估轮胎化学品环境命运和运输的测试策略:a） 轮胎硫化过程中胎面中化学添加剂的转化；b） TRWP生成过程中化学添加剂的转化（轮胎使用）；c） TRWP老化和风化过程中化学添加剂的转化；d） 从TRWP向水中浸出化学添加剂和转化产物；e） 沉积物生态系统中TRWP化学添加剂和转化产物的可用性。使用TRWP在五个生命周期步骤中释放或可用的化学品的质量浓度和分数进行估算a） 释放到水中的胎面化学品和转化产物的累积分数，以及b） 累积分数胎面化学品和转化产品环境可用。

This document establishes a general framework and considerations for assessing the environmental fate of tyre tread chemical additives in cured polymer and tyre and road wear particles (TRWP) throughout a tyre lifecycle. This document is applicable to laboratory-generated TRWP from cured tread polymer of known composition.Testing strategies are described for assessing the environmental fate and transport of tyre chemicals in the following processes that can occur during the tyre lifecycle:a) transformation of chemical additives in tread during tyre curing;b) transformation of chemical additives during TRWP generation (tyre use);c) transformation of chemical additives during TRWP aging and weathering;d) leaching of chemical additives and transformation products from TRWP to water;e) availability of chemical additives and transformation products from TRWP in sediment ecosystems.Mass concentrations and fractions of chemicals released or available from TRWP for the five lifecycle steps are used to estimatea) cumulative fraction of tread chemical(s) and transformation product(s) released to water, andb) cumulative fraction tread chemical(s) and transformation products(s) environmentally available.
