Pigments and extenders - Determination of experimentally simulated nano-object release from paints, varnishes and pigmented plastics

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
