Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
The possible release of nano-objects (nanoscale pigments and extenders) from paints, varnishes and
pigmented plastics into surrounding air or liquid is an important consideration in health and safety,
for the end user and the environment. Therefore, it is important to obtain data about the propensity of
[10]
pigmented paints and plastics to release nano-objects, thereby allowing exposure to be evaluated ,
controlled and minimized. This property will likely depend on both the physico-chemical properties of
the nano-objects and the matrix containing the nano-objects.
The currently available methods to assess the propensity of pigmented paints, varnishes and plastics
