What is the purpose of a pull test in door hardware?

• A. To verify that latches and locking mechanisms hold under typical operating loads and vibrations
• B. To measure door weight
• C. To adjust door hinges
• D. To test paint finish

Answer: (A)

This test checks that door hardware remains secure when the door is subjected to the kinds of forces it experiences in daily use: pulling, opening, closing, and any vibrations from operation or nearby activity. The goal is to ensure that the latch, strike, and locking components stay engaged and continue to function reliably under those typical loads, so the door cannot be unexpectedly forced open or fail to latch properly. It helps identify wear, loose fasteners, misalignment, or weak springs that could compromise security or safety. It isn’t about measuring door weight, adjusting hinges, or evaluating paint finish, which are unrelated to how the latch and lock hold under normal or anticipated dynamic forces.
