标准范围

ISO 19403-2:2017规定了一种测量接触角的试验方法，用于测定固体表面的表面自由能。该方法可用于基材和涂层的表征。注1:为了测定聚合物和涂层的表面自由能，最好使用符合Owens、Wendt、Rabel和Kaelble的方法或符合Wu的方法。注2:形态和化学均匀性对测量结果有影响。注3:ISO 19403-2:2017中规定的程序基于最先进的半影投影法。其他方法也不排除在外。注4:测量粉末接触角不属于ISO 19403-2:2017的一部分。有关更多信息，请参阅参考书目。

ISO 19403-2:2017 specifies a test method to measure the contact angle for the determination of the surface free energy of a solid surface. The method can be applied for the characterization of substrates and coatings.NOTE 1 For the determination of the surface free energy of polymers and coatings, either the method in accordance with Owens, Wendt, Rabel and Kaelble or the method in accordance with Wu is used preferably.NOTE 2 The morphological and chemical homogeneity have an influence on the measuring results.NOTE 3 The procedures indicated in ISO 19403-2:2017 are based on the state-of-the-art employing the drop projection method in penumbral shadow. Other methods are not excluded.NOTE 4 Measuring the contact angle on powders is not part of ISO 19403-2:2017. For further information, see the bibliography.
