Burglary Ratings Explained

U.L. Label — Burglary Classification TL-15:

TL-15 Label

Signifies a combination-locked safe designed to offer a limited degree of protection against attack by common mechanical and electrical hand tools and any combination of these means.

Construction Requirements

  • U.L. listed Group II, 1 or 1R combination lock.
  • 750 lbs. minimum or comes with instructions for anchoring in a larger safe, concrete blocks 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 P.S.I.
  • Walls fastened in a manner equivalent to continuous ¼” penetration weld of open hearth steel with minimum tensile strength of 50,000 P.S.I.
  • One hole ¼” or less, to accommodate electrical conductors arranged to have no direct view of the door or locking mechanism.

Performance Requirements
Successfully resist entry* for a net working time of 15 minutes when attacked with common hand tools, picking tools, mechanical or portable electric tools, grinding points, carbide drills and pressure applying devices or mechanisms.

U.L. Label —Burglary Classification TL-30:

TL-30 Label

Signifies a combination-locked safe designed to offer a moderate degree of protection against attack by common mechanical and electrical hand tools and any combination of these means.

Construction Requirements
Same as TL-15

Fire Ratings Explained
U.L. FIRE RESISTIVE RATINGCLASSIFICATIONTHE FOLLOWING IS AN EXPLANATION OF THE UNDERWRITER’S LABORATORIES’ FIRE RESISTANT CONTAINER TESTING PROCEDURES ON THE CLASS 350°F, ONE HOUR AND TWO HOUR FIRE LABELS.U.L. Label/Class 350°F-one hour and Class 350°F-two hour. The safe will maintain an interior temperature less than 350°F when exposed to fire for a period of one hour at 1700°F or for a period of two hours at 1850°F. Safe must successfully undergo all other requirements for the Fire Endurance Test, Explosion Hazard Test and the Fire/Impact Test as stated below.FIRE ENDURANCE TEST
After heat sensors and paper are placed inside the safe, the unit is locked and exposed to a uniformly distributed fire. The furnace is regulated to reach a maximum temperature of 1700°F for a period of one hour, or 1850°F for two hours, then allowed to cool without opening the furnace. The interior temperature is recorded throughout the test and during the cooling period until a definite drop is shown and must never exceed 350°F.Once cooled, the unit is opened and examined for usability. The units locking mechanisms and parts fastenings are examined for security and the interior examined for visible evidence of undue heat transmission.

EXPLOSION HAZARD TEST
The safe is locked and placed into a furnace preheated to 2000°F. This temperature is maintained for 30 minutes (2 hour test is 45 minutes) and if no explosion results, the unit is allowed to cool without opening the furnace doors. Once cooled, the unit is opened and examined for usability. The units locking mechanisms and parts fastenings are examined for security and the interior examined for visible evidence of undue heat transmission.FIRE IMPACT TEST
(MANUFACTURER’S OPTION)
After the explosion hazard test the safe is removed from the furnace and within two minutes is dropped 30’ onto a riprap of brick on a heavy concrete base. After impact the unit is examined for deformation, rupture of parts, damaged insulation and any other openings into the interior of the unit. Once cooled, the unit is inverted and reheated to 1550°F for a period of 30 min. (2 hour test: 45 min. at 1638°F).
Once cooled, the unit is opened and examined for usability. The units locking mechanisms and parts fastenings are examined for security and the interior examined for visible evidence of undue heat transmission.		  Fire Rating Thermometer
