scope:

This standard shall cover the 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.

This standard is based on product and engineering practices recognized as being acceptable at the date of issue. Therefore, provisions of this standard are not intended to be applied retroactively to installations which were in compliance at the time of installation.

NOTE: The authority having jurisdiction may require upgrading of existing installations to meet current standards and requirements only when the lack of compliance with this standard presents a serious fire or life safety hazard. It should be noted that care and maintenance of materials for ongoing and existing installations should be maintained in accordance with the standards under which they were installed.

Incinerator doors, record room doors, and vault doors are not covered in this standard. For their installation, see NFPA 82, Standard on Incinerators, Waste and Linen Handling Systems and Equipment, NFPA 232, Standard for the Protection of Records, and NFPA 81, Standard for Fur Storage, Fumigation and Cleaning.

For standards on the installation of hoistway doors for elevators and dumbwaiters see the applicable sections of ANWASME A17.1, Safety Code for Elevators and Escalators (1981 edition). (See Appendix D, Section 0-1.5.
