Standard Test Method for Measurement of Dry Film Thickness of Thin-Film Coil-Coated Systems by Destructive Means Using a Boring Device

Importancia y uso:

3.1 Measurement of dry film thickness of organic coatings by physically cutting through the film and optically observing and measuring the thickness offers the advantage of direct measurement as compared with nondestructive means.

3.2 Constituent coating layers can usually be measured individually by this test method, provided adhesion between each layer is sufficient. However, this can be difficult in cases where the primer, topcoat, or multiple coating layers have the same, or very similar, appearance.
