GENERAL

This category covers file-room doors consisting of an assembly of insulated doors closing into and interlocking with an insulated frame and equipped with a locking mechanism. These doors are effective in withstanding:

1. A standardized fire of controlled extent and severity for at least 1 h (reaching 1700°F) or 1/2 h (reaching 1550°F) without exceeding an interior temperature of 350°F during or after the fire exposure, 36 in. from the unexposed face of the door or 6 in. to the side from the door joints, when installed in accordance with the manufacturer's instructions.
2. Application of a standard hose stream and reheat for 1/2 of the classification period without destroying the usability of paper records stored in the file room.

File-room doors are intended to be installed in file rooms constructed as specified in ANSI/NFPA 232, "Protection of Records." A file room is a fire-resistive enclosure in a fire-resistive building, the enclosure having less fire resistance than a standard vault. The enclosure is intended to be used exclusively for the storage and handling of records.
