configuration. Bonds are then conditioned for 24 hours at 70°F (22°C), 50% relative humidity before
testing. Bonds are subjected to 2 lbs. per square inch load at 100°F (49°C) for 30 minutes.
Temperature of the bond line is raised every 30 minutes until failure. Heat resistance recorded is the
last temperature prior to bond failure.
