ASTM D3359 provides tape-test methods for rating adhesion of relatively ductile coatings on metallic substrates. The coating is cut in a defined manner, pressure-sensitive tape is applied and removed, and the affected coating area is visually rated using the applicable classification system. The standard contains different test approaches depending on coating thickness and test configuration. Test Method A is primarily intended for coating systems greater than 125 µm total thickness. Test Method B is primarily intended for coating systems less than 125 µm total thickness. For films above 125 µm, Method B is not considered suitable unless wider-spaced cuts are used and this has been explicitly agreed between the relevant parties.
