Summary
This document specifies a test method for determining the polar and dispersive fractions of the surface tension of liquids using optical methods. This method can be used for the characterization of liquid paint products. Its applicability may be limited for liquid products with non-Newtonian rheology[1]. This document assumes that the information relating to the surface tension of the liquid to be tested and the surface free energy of the solids used as a reference for the dispersion contribution are known. [1] This term is defined in standard DIN 1342-1.
