Scope

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. If applied to liquids with non-Newtonian flow behaviour (as defined in ISO 3219-1:2021, 3.22), restrictions can apply.
NOTE       For other methods to determine the surface tension, see e.g. EN 14370 and ISO 1409.
