BS EN ISO 26423:2016规定了一种测定陶瓷涂层厚度的方法——弧坑磨削法，包括球形空腔的磨削和随后对弧坑的显微镜检查。由于弹坑尺寸测量中引入的不确定性，该试验不适用于涂层和/或基材的表面粗糙度超过涂层厚度20%的情况。注:ISO 18452中给出了使用接触探针轮廓仪测量厚度的替代方法。交叉引用:ISO 3290-1ISO/IEC 17025:2005 ISO 18452包含以下内容:勘误表，2016年7月

BS EN ISO 26423:2016 specifies a method for the determination of the thickness of ceramic coatingsbyacrater-grinding method, which includes the grinding of a spherical cavity and subsequent microscopicexamination of the crater.Because of the uncertainty introduced into the measurement of crater dimensions, the test is not suitable foruse where the surface roughness of the coating and/or substrate exceeds 20 % of the coating thickness.NOTE An alternative method for measurement of thickness, using a contact probe profilometer, is given in ISO 18452.Cross References:ISO 3290-1ISO/IEC 17025:2005ISO 18452Incorporates the following:Corrigendum, July 2016
