This International Standard describes a number of methods that are applicable to the measuremen of 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．Reference is made to individual standards
where these exist．Otherwise the method is described in devil．
An overview on the methods is given in Annex A，in which the field of application，existing standards and the
precision are specified for the individual methods．
This International Standard also defines terms concerning the determination of film thickness.
