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.<\/p>\n

For each method described, this document provides an overview of the field of application, existing standards and the precision.<\/p>\n

Information on measuring film thickness on rough surfaces is given in Annex\u00c2 B<\/span>.<\/p>\n

Information on measuring film thickness on wooden substrates is given in Annex\u00c2 C<\/span>.<\/p>\n
