ABSTRACT:
A method of testing the adhesion between a coating and its substrate applies a force to a sample by means of a plunger and supporting ring apparatus. The force is increased laterally while the force and the resulting deflection are measured. When the slope of the force-deflection curve changes abruptly, the test is terminated, and the value of force required to produce that condition is noted. The test is nondestructive.
