• Peeled at the rate of 12 inches (305 mm) per minute.
Note: In long term static load applications, conditions such as temperature variation, jarring,
vibration, etc., can affect long term performance. The user should design the amount of
fastening area based on the specific conditions in the application. Four square inches of
fastening area per pound of static load is suggested as a starting point for such evaluations.
