DESCRIPTION

BS EN ISO 19403-4:2024


This standard BS EN ISO 19403-4:2024 Paints and varnishes. Wettability is classified in these ICS categories:
  • 01.040.87 Paint and colour industries (Vocabularies)
  • 87.040 Paints and varnishes
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.
