Paints and varnishes - Wettability - Part 2: Determination of the surface free energy of solid surfaces by measuring the contact angle (ISO 19403-2:2024)
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.
Beschichtungsstoffe - Benetzbarkeit - Teil 2: Bestimmung der freien Oberflächenenergie fester Oberflächen durch Messung des Kontaktwinkels (ISO 19403-2:2024)
Dieses Dokument legt ein Prüfverfahren zum Messen des Kontaktwinkels für die Bestimmung der freien Oberflächenenergie einer festen Oberfläche fest. Das Verfahren kann zur Charakterisierung von Substraten und Beschichtungen eingesetzt werden.
ANMERKUNG 1 Zur Bestimmung der freien Oberflächenenergie von Polymeren und Beschichtungen wird bevorzugt entweder das Verfahren nach Owens, Wendt, Rabel und Kaelble [3] [4] [5] oder das Verfahren nach Wu angewendet.
ANMERKUNG 2 Die morphologische und die chemische Homogenität haben einen Einfluss auf die Messergebnisse. Die in diesem Dokument dargestellten Vorgehensweisen basieren auf dem Stand der Technik bei der Anwendung des Tropfenprojektionsverfahrens im Halbschattenbild. Andere Verfahren sind nicht ausgeschlossen.
Die Messung des Kontaktwinkels an Pulvern ist nicht Bestandteil dieses Dokumentes.
Peintures et vernis - Mouillabilité - Partie 2: Détermination de l'énergie libre de surface des surfaces solides par la mesure de l'angle de contact (ISO 19403-2:2024)
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 document 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).
