ABSTRACT:
An apparatus for applying a consistently perpendicular tension force to a dolly is provided for testing of the adhesive bond strength between a coating and a substrate. The tester comprises a ram passing through an axially centered opening in a dolly bonded to the coating. Piston and cylinder means 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 its coaxially centered orientation with respect to the ram.
