2 Hour - U.L class 350 Rate Safe |
The safe is heated for two hours to reach an exterior temperature of 1550 degrees, then put through the cool down test. During the complete process the interior of the safe cannot drop below 350 degrees. At U.L. after the safe has hit the test time the safe is removed from the oven and hoisted 30 feet (equal to 3 flights of a building) and dropped on to concrete rubble, it is allowed to cool and then picked up and placed back into a 2000 degree preheated oven (this is called the explosive test). It is done to see if the door will blow off, then it remains in the oven and the contents of the safe must come out unharmed.
