DESCRIPTION
CSN EN ISO 19403-4
CSN EN ISO 19403-4 This document specifies a test method to determine the polar and dispersive fractions 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. Original English text of CSN EN Standard. The price of the Standard included all amendments and correcturs.
