Peintures et vernis — Mouillabilité — Partie 5: Détermination des fractions polaire et dispersive de la tension superficielle des liquides à partir de mesurages de l'angle de contact avec un solide n'ayant qu'une contribution de dispersion à son énergie de surface

Abstract / scope

This document 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.

If applied to liquids with non-Newtonian flow behaviour (see ISO 3219-1:2021, 3.22), restrictions can apply.
