GENERAL

This category covers record protection equipment consisting of self-contained devices that incorporate insulated bodies, doors, drawers or lids, or nonrated multidrawer devices housing individually-rated containers that contain one or more inner compartments for storage of records. These devices are intended to provide protection to one or more types of records as evidenced by the assigned Class rating or ratings: Class 350 for paper, Class 150 for magnetic computer tapes and photographic film, and Class 125 for flexible disks. Inner compartments of record protection equipment may bear labels indicating the Class ratings, if different from the Class rating of the basic outer unit.

Record protection equipment is effective in withstanding:

1. A standardized fire of controlled extent and severity for one of the following periods: 4 hr reaching 2000°F, 2 hr reaching 1850°F, 1 hr reaching 1700°F, or 1/2 hr reaching 1550°F depending upon its hourly rating, before the interior temperature of the compartment exceeds the rated Class temperature (350°F, 150°F or 125°F) during the period of fire exposure and the cooling period inside the furnace after the fire exposure.

2. A sudden heating at 2000°F for 30 min (20 min for units rated 1/2 hr) without producing an explosion sufficient to cause an opening into the interior and without destroying the usability of paper contents.

3. At the option of the manufacturer, and as indicated in the individual Classifications, an impact due to falling 30 ft in the clear after being heated for 60 min, 45 min, 30 min or 20 min for devices rated 4, 2, 1 and 1/2 hr, respectively; and reheating in the inverted position for the same length of time (60 min, 45 min, 30 min or 20 min) after the impact without destroying the usability of the papers stored inside.

UNEVALUATED FACTORS

The ability of nonpaper records to withstand the exposure, or store or retain data has not been investigated.

These devices have not been investigated for their acceptability of use after exposure to fire and being impacted.

Devices that have been investigated for security protection are covered under the following:

Residential Security Containers (TQDE)

Tool-resistant Safes, Class TL-15 (TQMZ)

Tool-resistant Safes, Class TL-15X6 (TQQM)

Tool-resistant Safes, Class TL-30 (TRAX)

Tool-resistant Safes, Class TL-30X6 (TREL)

ADDITIONAL INFORMATION

For additional information, see Record Protection Devices (RWIT) and Fire Protection Equipment (AAFP).

REQUIREMENTS

The basic standard used to investigate products in this category is ANSI/UL 72, "Tests for Fire Resistance of Record Protection Equipment."

UL MARK

The Classification Mark of Underwriters Laboratories Inc. on the product is the only method provided by UL to identify products manufactured under its Classification and Follow-Up Service. The Classification Mark for these products includes the UL symbol, the word "CLASSIFIED" above the UL symbol (as illustrated in the Introduction of this Directory), and the following additional information:

or

When individual compartments are investigated, the Classification Mark will also include the following statement:

+ 350, 150 or 125

++ 1/2, 1, 2, 3 or 4
