Paints and varnishes - Wettability - Part 5: Determination of the polar and dispersive fractions of the surface tension of liquids from contact angles measurements on a solid with only a disperse contribution to its surface energy (ISO 19403-5:2017)

ISO 19403-5:2017 specifies a test method to determine the polar and dispersive fractions of the surface tension of liquids by optical methods. The method can be applied for the characterization of liquid coating materials.
The applicability can be restricted for liquids with non-Newtonian rheology[1].
ISO 19403-5:2017 assumes that the information of surface tension of the liquid to be tested and the surface free energy of the dispersive reference solids is known.
[1] This term is defined in DIN 1342-1.

Beschichtungsstoffe - Benetzbarkeit - Teil 5: Bestimmung des polaren und dispersen Anteils der Oberflächenspannung von Flüssigkeiten aus Kontaktwinkelmessungen auf einem Festkörper mit rein dispersem Anteil der Oberflächenenergie (ISO 19403-5:2017)

Dieses Dokument legt ein Prüfverfahren mit optischen Verfahren zum Bestimmen des polaren und dispersen Anteils der Oberflächenspannung von Flüssigkeiten fest. Das Verfahren kann zur Charakterisierung von flüssigen Beschichtungsstoffen eingesetzt werden.
Die Anwendbarkeit bei Flüssigkeiten mit nicht-newtonschem Fließverhalten1 kann eingeschränkt sein.
Dieses Dokument geht davon aus, dass die Oberflächenspannung der zu prüfenden Flüssigkeit und die freie Oberflächenenergie der dispersen Referenzflüssigkeit bekannt sind.

Le présent document spécifie une méthode d'essai permettant de déterminer les fractions polaire et dispersive de la tension superficielle des liquides à l'aide de méthodes optiques. Cette méthode peut être utilisée pour la caractérisation des produits de peinture liquides.
Son applicabilité peut être limitée pour les produits liquides de rhéologie non newtonienne[1].
Le présent document présuppose que les informations relatives à la tension superficielle du liquide à soumettre à essai et que l'énergie libre de surface des solides servant de référence pour la contribution de dispersion sont connues.
[1] Ce terme est défini dans la norme DIN 1342-1.

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
