Annotation of standard text ČSN EN ISO 21683 (671419):

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
