Abstract
A method of coating testing comprises applying a consistantly perpendicular minimum tension force to a dolly for testing to see if the adhesive bond strength between a coating and a substrate meets a minimum specification for such bond. The tester comprises a ram passing through an axially centered opening in a dolly bonded to the coating. A piston and cylinder are associated with the ram and the dolly so that pressure within the piston chamber formed thereby causes the development of a tension force within the dolly which is perpendicular to the coating being tested because of the coaxially centered orientation of the dolly with respect to the ram. The pressure is increased only to a point wherein the tension force is equal to a minimum specification for bonding adhesion. If the coating has not separated from the substrate, the bond therebetween meets the specification. The testing apparatus may then be removed by causing the bonding agent attaching the dolly to the coating to fail as by heating.
