本文件描述了测量基底涂层厚度的方法。描述了测定未固化粉末层的湿膜厚度、干膜厚度和膜厚度的方法。 对于所述的每种方法，本文件概述了应用领域、现有标准和精度。 附件B中给出了粗糙表面上膜厚度的测量信息。 附录C中给出了测量木质基材上薄膜厚度的信息。

This document describes methods for measuring the thickness of coatings applied to a substrate. Methods for determining wet-film thickness, dry-film thickness and the film thickness of uncured powder layers are described. For each method described, this document provides an overview of the field of application, existing standards and the precision. Information on measuring film thickness on rough surfaces is given in Annex B. Information on measuring film thickness on wooden substrates is given in Annex C.
