ABSTRACT
This document specifies a method for the experimental determination of the release of pigments and fillers at the nanoscale in the environment, following the application of a mechanical stress on paints, varnishes and pigmented plastics. This method assesses whether particles of defined size and distribution under stress (type and intensity of applied energy) are released from surfaces and emitted into the environment. It also makes it possible to determine the number of particles released. The samples are aged, subjected to the elements or otherwise conditioned to simulate their entire life cycle.
