Anti-magnetic test: use 150 lb force magnet to test the anti-magnetic interference ability of the lock cylinder
Mechanical Strength Test: simulate the repeated opening and closing of the door (e.g., 10,000 cycle test) to verify durability Fire and burglary resistance
Fire protection locks need to meet the emergency mechanism of keeping locked (fail-safe lock) or unlocked (fail-safe lock) after a power failure
