ABSTRACT:
An adhesive is applied to overlapping portions of a two-part test sample located between opposing press heads of the bond testing device. The press heads then press together the overlapping portions for a specific period of time while heating the test sample to a preselected temperature. The device precisely maintains the temperature while bonding the sample at a preselected pressure. A load cell measures the shear force required to separate the bonded test piece.
