ASTM D4541 Pull-Off Strength of Coatings Using Portable Adhesion Testers

ASTM D4541 tests evaluate the pull-off strength or adhesion of a coating on materials such as metal, concrete or wood. The results show either, the greatest tension force the a surface can handle before a material is detached or if the surface remains intact after a certain amount of force. This test maximizes tensile stress rather than shear stress applied by other methods. Measurements can depend on both the material and instrumental parameters. There is a possibility of the use of five different instruments during this test. ASTM D4541 can be destructive and may require some repairs prior to the test.
