Hammering and punching test
Side drilling and punching the bolts test
- UL hires professional safe crackers try and breach the security of safes. For home and gun safes, UL uses a variety of tests to breach the security of a safe.
- Test methods can include: prying, drilling, punching, chiseling, and tampering attacks to the safe's lock, handle, mechanism and body of the safe. UL even gets to view the engineering drawings prior to the test, thus giving them a head start in knowing where to drill.
- UL has the advantage of opening the safe door and removing the door panel to analyse the safe's security features and positions. Once they develop a strategic plan with measurements to more accurately attack the safe, they close the door and have 5 minutes to break-in. This 5 minute test is a timed test. If they take a break, the clock stops and restarts again once they begin the onslaught.
- If UL cannot breach the security of the safe within the time period, that series of safes receive UL's Residential Security Container (RSC) certification and accompanying certification number. If a safe does not pass, it's back to the drawing board.
- Some of the tests utilized in UL's testing include:
- Drilling the lock's tumblers attempting to make the lock act as if the combination was dialed.
- Pry the dial off and knock out the lock tumblers through the lock's back plate permitting the locking bolt to retract.
- Punch in the handle shaft to push out the cam/gear mechanism in order to bypass the lock.
- Cut a 4" hole in the side of the safe body by drilling an X and punching through with a sledge hammer. Access through the side to side punch the locking bolts may be attempted to break the lock or mechanism.
- In every case, Liberty Safes that currently bear the UL symbol of security protected against entry and received UL's Residential Security Container (RSC) certification.
- In the following security pages, we will show the security features that made this possible.
