Abstract
A ceramic tile shear testing apparatus and method of use. The apparatus includes a frame with a hydraulic cylinder for moving a shearing member extending outwardly of the frame. The apparatus may be placed on a bonding layer on a working surface adjacent a tile to be tested and the hydraulic cylinder actuated to apply a force to the tile in a direction parallel to the working surface sufficient to break the bond holding the tile to the surface. Pressure in the hydraulic cylinder may be measured when the shear occurs as a correlation of the shear strength of the bond.
