DESCRIPTION
UNE EN ISO 19403-3:2025
This document specifies a test method to measure the surface tension of liquids with an optical method using the pendant drop. The method can be applied for the characterization of liquid coating materials. The applicability can be restricted for liquids with non-Newtonian flow behaviour1). NOTE For other methods to determine the surface tension, see e.g. EN 14370 and ISO 1409.
