Paints and varnishes — Wettability — Part 5: Determination of the polar and dispersive fractions of the surface tension of liquids from contact angles measurements on a solid with only a disperse contribution to its surface energy
色漆和清漆.润湿性.第5部分:从接触角测定液体表面张力的极性和分散性部分.对仅对其表面能有分散作用的固体的测量
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 ISO3219-1:2021, 3.22), restrictions can apply.
