This document specifies a test method to determine the polar and dispersive fractions of the surface tension of liquids by optical methods. The method can be applied for the characterization of liquid coating materials.
If applied to liquids with non-Newtonian flow behaviour (see ISO 3219‑1:2021, 3.22), restrictions can apply.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
