UL Ratings
UL stands for Underwriters Laboratories, an independent organization dedicated to educating businesses and the public about safety and performance of products in a wide spectrum of industries. UL has been testing and rating products for more than 100 years, and evaluates nearly 20,000 products annually. The UL rating is an indicator of product quality and certification of safety.
Safe Ratings
B-Rated: Has at least a 1/4″ steel body, 1/2 inch door. No tests are given to provide this rating. Look at the lock work, relockers, and other features when making your decision.
TL-15: The label means that the safe successfully resisted entry for a NET working time of 15 minutes using common hand tools, drills, punches, hammers, and pressure applying devices.
- UL listed Group II, 1, or 1R combination lock. In addition, these safes may be provided with UL Listed High Security electronic locks.
- Must be 750 pounds minimum or comes with anchoring instructions in a larger safe, concrete block, or on the premises where used.
- Body walls of material equivalent to at least 1″ open hearth steel with a minimum tensile strength of 50,000 PSI.
- Walls fastened in a manner equivalent to continuous 1/4″ penetration weld of open hearth steel with a minimum tensile strength of 50,000 PSI.
- One hole 1/4″ or less to accommodate electrical conductors arranged to have no direct view of the door or locking mechanism.
TL-30: Construction requirements are identical to the TL-15 above. Tests are essentially the same as the TL-15 tests except for the net working time. Testers are allowed 30 minutes and a few more tools (abrasive cutting wheels and power saws) to help them gain entrance. The label signifies the testers were unable to open the door or make a 6″ square opening entirely through the door or front face within 30 minutes.
TL30x6: The TL-30 (30-minute) test is conducted on all six (6) sides of the safe. This test signifies that a combination-locked safe is designed to offer a full six-sided body and door protection against an attack by common mechanical and electrical hand tools and any combination of these means.
- UL Listed Group 2M, 1, 1R combination lock or Type 1 electronic lock.
- It must be 750 pounds minimum or comes with anchoring instructions in a larger safe, concrete block, or on the premises where used.
- Body walls of material equivalent to at least 1″ open hearth steel with a minimum tensile strength of 50,000 PSI.
- Walls fastened in a manner equivalent to continuous 1/4″ penetration weld of open hearth steel with a minimum tensile strength of 50,000 PSI.
- One hole 1/4″ or less to accommodate electrical conductors arranged to have no direct view of the door or locking mechanism.
TRTL-30×6: The TR in the TRTL-30-X6 stands for torch resistance. This means that the safe is torch resistant on all six sides of the safe. The TL stands for tool resistance. This means that the safe is tool resistant on all six sides of the safe. This is one of the highest burglar ratings on the market.
Fire Rating: Fire ratings are evaluated by testing to see if safes withstand varying furnace heat for specific amounts of time. For example, the UL Class 350 1-hour fire rating means that the internal temperature of the safe will not exceed 350°F for at least 1 hour when exposed to external temperatures over 1700°F. A safe may have a 1-, 2-, or 3-hour time classification. Additionally, safes will be heated and then dropped from heights reaching 30 feet to test against explosions.
