标准摘要
[中文适用范围]： 该文件规定了一种测试方法，通过光学方法确定液体表面张力的极性分量和分散分量，从界面张力测量中得出。该方法适用于液体涂层材料的表征，特别是在替代测量过程中发生干燥效应时。如果应用于具有非牛顿流动行为的液体（参见ISO 3219-1:2021, 3.22），可能会受到限制。 [外文原描述]： 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.
