UL Certification For Safes
Underwriters Laboratories (UL) testing certifications for safes are known to be the some of the most rigorous and most respected in the world. They are only matched by B.T.U/V.D.M.A. certifications (Germany). J.I.S. (Japan) and CSTB (France) preheat the oven with the safe inside until the temperature reaches the desired setting (as opposed to a sustained temperature of the rating), then the safe is cooled artificially (as opposed to naturally). Also, J.I.S. and CSTB only drop their safes from 13-15 feet (as opposed to 30). Rarely are safes dropped 15 feet (4.6 m) or more and they are usually artificially cooled by the fire department. UL also runs an indirect explosion test on all safes. Additionally UL-768 certifies the combination lock against tampering. UL-140 certifies a relocking mechanism that will permanently lock the safe bolts, in case an electronic lock fails or a UL-768 rated lock is compromised.
