Pigments and extenders - Determination of experimentally simulated nano-object release from paints, varnishes and pigmented plastics (ISO 21683:2019)
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.
Pigmente und Füllstoffe - Bestimmung der experimentell simulierten Freisetzung von Nanoobjekten aus Beschichtungen und pigmentierten Kunststoffen (ISO 21683:2019)
Dieses Dokument legt ein Verfahren zur experimentellen Bestimmung der Freisetzung von nanoskaligen Pigmenten oder Füllstoffen in die Umgebung nach einer mechanischen Beanspruchung von Beschichtungs-stoffen und pigmentierten Kunststoffen fest.
Das Verfahren wird angewendet, um zu bewerten, ob und wie viele Partikel bestimmter Größe und Ver-teilung unter Beanspruchung (Art und Höhe der zugeführten Energie) von Oberflächen freigesetzt und in die Umgebung abgegeben werden.
Die Proben werden gealtert, bewittert oder anderweitig konditioniert, um den gesamten Lebenszyklus zu simulieren.
Pigments et charges - Détermination par simulation expérimentale de la libération de nano-objets par les peintures, vernis et plastiques pigmentés (ISO 21683:2019)
Le présent document spécifie une méthode de détermination expérimentale de la libération de pigments et de charges à l'échelle nanométrique dans l'environnement, suite à l'application d'une contrainte mécanique sur les peintures, vernis et plastiques pigmentés.
Cette méthode permet d'évaluer si des particules de taille et de distribution définies soumises à contrainte (type et intensité de l'énergie appliquée) sont libérées par les surfaces et émises dans l'environnement. Elle permet également de déterminer le nombre de particules libérées.
Les échantillons sont vieillis, soumis aux intempéries ou sinon conditionnés de manière à simuler la totalité de leur cycle de vie.

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.

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
