DIN Standards Committee Coatings and Coating Materials

Abstract

This document specifies a test method to determine the polar and dispersive fraction of the surface tension of liquids from an interfacial tension with optical methods. The method can be applied for the characterization of liquid coating materials, especially if drying effects occur during alternative measurement. If applied to liquids with non-Newtonian flow behaviour (see ISO 3219-1:2021, 3.22), restrictions can apply.
