About This Item

 

Full Description



These requirements cover the test procedures applicable to the fire-resistance classification of record protection equipment intended to provide protection to one or more types of records when exposed to various durations of fire exposure.

Record protection equipment consists of self-contained, moveable devices of varying configurations, such as insulated bodies with insulated doors or drawers or lids, nonrated multidrawer devices housing individually rated drawer bodies, and other similar constructions.

Tests conducted in accordance with these requirements are intended to demonstrate the performance of record protection equipment during exposure to fire, but are not intended to determine acceptability for use after fire exposure.

Under these requirements, record protection equipment is exposed to a fire endurance test and an explosion test. Equipment intended to provide impact resistance is also exposed to a fire and impact test. The fire endurance test is intended to demonstrate the ability of the device to prevent the development of temperatures and relative humidity (Classes 125 and 150 only) exceeding the specified limits inside the device for the classification desired. The explosion test is intended to demonstrate the ability of the device to withstand a sudden exposure to high temperatures and prevent an explosion of the device from a buildup of steam or other gases. The fire and impact test is intended to demonstrate the ability of the device to protect contents from heat, to the extent described in the requirements, before and after an impact due to falling 30 feet (9.1 m).
