Paints and varnishes -- Determination of film thickness
ISO 2808:2007 describes a number of methods that are applicable to the measurement 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 detail.
The standard also defines terms concerning the determination of film thickness.
