scope:

This Standard covers the use, installation, and maintenance of fire door assemblies, windows, glass blocks and shutters for the protection of openings in walls to restrict the spread of fire and smoke within buildings whether from interior fire or from external fire, including arrangements for automatic operation in case of fire. It is not intended to establish the degree of protection required or to constitute the approval of any product.

Incinerator doors, record room doors and vault doors are not covered in this Standard. For their installation, see Standard on Incinerators and Rubbish Handling (NFPA 82, see Appendix D) ; Standard for the Protection of Records (NFPA 232, see Appendix D) ; and Standard for Fur Storage, Fumigation and Cleaning (NFPA 81, see Appendix D).

For standards on the installation of hoistway doors for elevators and dumbwaiters, see Safety Code for Elevators, Dumb-waiters, Escalators, and Moving Walks (ANSI A17.1, see Appendix D), Section 110.

New Developments: This standard shall not act as an obstruction to the development of new, modified or improved devices which meet the intent of these requirements. It shall be the responsibility of the manufacturer to furnish the necessary information to effect the updating of the requirements pertaining to such new and improved devices.¹

For devices not described in this Standard, the authority having jurisdiction shall request from manufacturers descriptive information provided by nationally recognized testing laboratories concerning acceptable methods for satisfactory field installation, based on fire tests and engineering studies for operation and maintenace consideration, where applicable.

 ¹The development of fire doors and related devices is a continuous process, therefore this Standard cannot be up to date at all times. This Standard is intended to be current only to the date of publication.
