Zusammenfassung:	Disclosed is an apparatus for applying a consistantly perpendicular tension force to a dolly 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.
