This test method is described by the ASTM standard C633-13.
An alternative approach allows measurement of coating adhesion on flat plate specimens. The test uses apparatus known as a portable pull-off adhesion tester and follows the method described by the ASTM standard D 4541 - 02. The adhesion tester uses a micro hydraulic system to apply a tensile load to a cylindrical test piece that is adhesively bonded to the coating surface. The pull force is distributed evenly and dynamically through the test specimen. The force is increased while balanced continually between the four hydraulic legs until fracture occurs.
