Paints and varnishes - Wettability - Part 2: Determination of the surface free energy of solid surfaces by measuring the contact angle (ISO 19403-2:2017)
ISO 19403-2:2017 specifies a test method to measure the contact angle for the determination of the surface free energy of a solid surface. The method can be applied for the characterization of substrates and coatings.
NOTE 1 For the determination of the surface free energy of polymers and coatings, either the method in accordance with Owens, Wendt, Rabel and Kaelble or the method in accordance with Wu is used preferably.
NOTE 2 The morphological and chemical homogeneity have an influence on the measuring results.
NOTE 3 The procedures indicated in ISO 19403-2:2017 are based on the state-of-the-art employing the drop projection method in penumbral shadow. Other methods are not excluded.
NOTE 4 Measuring the contact angle on powders is not part of ISO 19403-2:2017. For further information, see the bibliography.

Le présent document spécifie une méthode d'essai permettant de mesurer l'angle de contact afin de déterminer l'énergie libre de surface d'une surface solide. Cette méthode peut être utilisée pour la caractérisation de substrats et revêtements.
NOTE 1 La détermination de l'énergie libre de surface de polymères et de revêtements se fait de préférence conformément à la méthode d'Owens, Wendt, Rabel et Kaelble ou à la méthode de Wu.
NOTE 2 L'homogénéité morphologique et chimique influe sur les résultats des mesurages.
NOTE 3 Les modes opératoires indiqués dans le présent document s'appuient sur les dernières techniques connues employant la méthode de projection de la goutte dans la pénombre. Les autres méthodes ne sont pas exclues.
NOTE 4 Le mesurage de l'angle de contact sur des poudres ne fait pas partie du présent document. Pour plus d'informations, voir la Bibliographie.

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
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
