Zusammenfassung:An apparatus for applying a consistently perpendicular tension force to a dolly 16 for testing of the adhesive bond strength between a coating 12 and a substrate 14 comprises a ram 34 passing through an axially centered opening 18 in the dolly 46 which is bonded to the coating 12. Piston and cylinder means 30,32 are associated with the ram and the dolly so that pressure within the piston chamber formed thereby forces the ram against the coating and causes the development of a tension force on the dolly 16 which is perpendicular to the coating 12 being tested because of its coaxially centered orientation with respect to the ram.
