Performance Ratings

UL established burglary (and fire) ratings that are regarded as the gold standard in the safe industry. In addition to setting standards of performance, many of UL’s burglary ratings specify construction requirements.

UNDERWATER LABORATORIES

Underwriters Laboratories (UL) is an independent product safety certification organization that has been testing products and writing standards for safety for more than a century. UL evaluates more than 19,000 types of products, components, materials and systems annually with 20 billion UL Marks appearing on 66,000 manufacturers' products each year. UL's worldwide family of companies and network of service providers includes 68 laboratory, testing and certification facilities serving customers in 102 countries.

BELOW ARE DESCRIPTIONS OF THE MOST COMMON UL BURGLARY CLASSIFICATIONS:

UL LABEL – RESIDENTIAL SECURITY CONTAINER (RSC)

Performance Requirements

Indicates the ability to withstand 5 full minutes of rigorous prying, drilling, punching, chiseling, and tampering attacks by UL technicians.

UL LABEL – BURGLARY CLASSIFICATION TL-15

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.

Only safes can provide the extra security you need.

Construction Requirements

• UL listed Group II, 1 or 1R combination lock (even the locks are tested and rated by UL).
• 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.

UL LABEL – BURGLARLY CLASSIFICATION TL-30

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

Performance Requirements

Successfully resist entry* for a net working time of 30 minutes when attacked with common hand tools, picking tools, mechanical or portable electric tools, grinding points, carbide drills and pressure applying devices or mechanisms, abrasive cutting wheels and power saws.

*Entry = opening the door or making a six square inch opening entirely through the door or front face.

FIRE RATINGS & CLASSIFICATIONS

Fire ratings and classifications involve three primary components; the maximum exterior temperature, length of time and maximum interior temperature. Underwriters Laboratories (UL) also tests for explosion hazard and offers optional testing for impact. When considering protection of electronic media, testing for humidity should also be done.

It is generally agreed that a maximum interior temperature of 350°F is adequate for most valuables, with paper charring at 450°F. Electronic media is more sensitive and therefore subject to a higher standard, commonly accepted to be either 150°F with a maximum 85% humidity or 125°F with a maximum of 80% humidity according to what type of electronic media being protected.

UL FIRE TESTING

UL offers the most comprehensive and stringent fire testing. Manufacturers can request their products be fire tested for up to three criteria; fire endurance, explosion hazard and impact. Passing the first two are required to carry a UL fire label, the third, impact, is optional.

Test products may be expected to protect a variety of different types of items for different lengths of time. To address these variables UL offers three different temperatures and five different time durations.

The temperature noted on the UL label (i.e. Class 350) indicates the maximum temperature reached on the interior of the safe during testing. Most valuables will be well protected in a safe that maintains an interior temperature of no more than 350°F. With paper charring at 450°F the 350°F maximum is usually adequate. Electronic media is more sensitive. For tapes, cartridges, microfiche, and microfilm, the limit is 150°F with an 85% humidity restriction; for diskettes, the temperature cannot exceed 125°F with an 80% humidity restriction.

The time noted on the UL label indicates how long the product was tested to withstand the extreme temperatures while maintaining the indicated maximum interior temperature and, if it applies, humidity.

The time rating also designates how hot the exterior temperature will get during the testing process. The product is placed in a furnace and the temperature rises over time.

There is a correlation between time and maximum temperature as follows:

Fire Endurance Test: Contents are distributed throughout the fire resistant product to be tested. UL uses heat sensors to monitor the internal temperature during testing. These are placed at the bottom, top and on all four side walls of the product being tested. Moisture sensors are used to measure humidity, with one placed 18 inches from the top and one 18 inches from the bottom, both midway between side walls.

For products testing to meet the Class 150 or 125 requirements, the product is first conditioned for at least twelve hours prior to the test. This conditioning ensures that the starting temperature of the interior will be between 65°F and 75°F and the relative humidity will be below 65%. This is considered to be equivalent to normal room conditions.

Depending upon the classification being tested, the furnace heat rises at a carefully monitored rate until the specified temperature is reached. Great care is taken to make sure the furnace heat is distributed evenly over the exposed surfaces of the products.

After the temperature and time is reached, for example one hour - 1700°F, the furnace is turned off. The test product is then allowed to cool in the unopened furnace until a significant decrease in the internal temperature is noted. This cooling process can take as long as 68 hours. During this cooling period, the tested product continues to absorb the heat in the furnace and the interior temperature of the product can continue to rise rapidly. It is during this critical point of the test that many products fail the test, particularly at the 125°F 80% humidity level. Only products whose internal temperature and humidity level remains below the test limits during the entire heating and cooling processes are awarded the label.

Finally, the product is opened and examined to determine whether the contents are still in usable condition. The interior walls and components are checked for any evidence of heat or humidity damage.

One year after this initial test has been conducted a sample product may be pulled out of production for retesting. The product must once again pass the original classification it was tested for to keep its UL label.

Fire and Impact Test

After a product has passed the Fire Endurance Test, another sample of the same product may be tested for fire and impact. The sample is prepared in the same manner as the Fire Endurance Test. Then it is heated to a specific time and temperature (see chart below). After the product has been exposed for the correct time period, it is immediately removed from the furnace and raised 30 feet off the ground. UL then drops the product within two minutes into a pile of broken brick on a concrete base. This is equivalent to a fall form a third story.

After the impact, the unit is carefully examined for any signs of deformation, rupture of insulation or parts, or openings into the interior of the product. Because products do not always land right-side-up in real life situations, the product is turned upside down after cooling. The product is then reheated to check exposure to heat.

Once the product has re-cooled, it is opened and dismantled. The testers examine the usability of contents, condition of the interior finish, security of locks, part fastenings and any signs of undue transmission of heat or moisture. One year later, UL may repeat this test on an identical product pulled from the production line.

The Explosion Test

All UL classified insulated record protection (this includes any safe that carries a UL fire resistance label) equipment must pass the explosion test. For this test, the sample is prepared in the same manner as for the two previous tests. The test furnace is left empty and heated to 2000°F. The testers quickly open the door and insert the sample. For 30 minutes (20 minutes for units rated ½ hour), the furnace is kept at 2000°F. If no explosion takes place, the sample remains in the furnace until it cools sufficiently to handle.

The sample is then forced to open and examined for heat or moisture damage. The interior finish, insulation, security or interior equipment, locks and fastening between parts, all undergo detailed inspection.

At the option of the manufacturer, the Impact and Explosion tests can be combined. The sample is inserted in the furnace to test for explosion, and then dropped 30 feet. The sample is then reheated and cooled again, and finally, examined carefully.

UL Fire Label

The UL Fire Label will look something like the following.
