颜料和填充剂.色漆、清漆和着色塑料试验模拟纳米物体释放量的测定

[中文适用范围]： 本文件规定了一种实验测定油漆、清漆和着色塑料机械应力后纳米级颜料和增量剂释放到环境中的方法。 该方法用于评估在压力（施加能量的类型和高度）下是否以及有多少具有规定尺寸和分布的颗粒从表面释放并排放到环境中。 样品经过老化、风化或其他处理以模拟整个生命周期。 [外文原描述]： This document specifies a method for experimental determination of the release of nanoscale pigments and extenders into the environment following a mechanical stress of paints, varnishes and pigmented plastics. The method is used to evaluate if and how many particles of defined size and distribution under stress (type and height of applied energy) are released from surfaces and emitted into the environment. The samples are aged, weathered or otherwise conditioned to simulate the whole lifecycle.
