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 rheology1).Cross References:ISO 15528:2013ISO 4618:2014ISO 19403-1:2017ISO 2811 (all parts)ISO 3270:1984 (R08)ISO 1409:2006ISO 19403-5:2017ISO 5725-2:2019BS ISO 5725-2:2019EN 14370:2004DIN 1342-1:1983 (Eng Trans)ISO 19403-4:2017ISO 19403-2:2017ISO 2808:2007Incorporates the following:Corrigendum, March 2020
