1.1* Scope. This standard regulates the installation and maintenance of assemblies and devices used to protect openings in walls, floors, and ceilings against the spread of fire and smoke within, into, or out of buildings. A.1.1 See Annex K for general information about fire doors. 1.1.1* With the exception of fabric fire safety curtain assemblies, this standard addresses assemblies that have been subjected to standardized fire tests. (See Chapter 20.) A.1.1.1 No fire test standard requirement currently exists to which fabric fire safety curtain assemblies can be tested. Only the curtain fabric is tested in accordance with ASTM E119, Standard Test Methods for Fire Tests of Building Construction and Materials. The perimeter and internal framework and all supporting, guide, and operating components used in specific applications are not tested. Variations in size of proscenium openings and the amount of side and head clearances available for individual stages dictate the number of variations in design of the assemblies. 1.1.2* Incinerator doors, record room doors, and vault doors are not covered in this standard. A.1.1.2 For requirements on their installation, see NFPA 82, Standard on Incinerators and Waste and Linen Handling Systems and Equipment, and NFPA 232, Standard for the Protection of Records. 1.1.3* Requirements for horizontally sliding, vertically sliding, and swinging doors as used in this standard do not apply to hoistway doors for elevators and dumbwaiters. A.1.1.3 For requirements on the installation of hoistway doors for elevators and dumbwaiters, see the applicable sections of ASME A17.1, Safety Code for Elevators and Escalators, or CSA B44, Safety Code for Elevators. 1.1.4* This standard does not cover fire resistantance glazing materials and horizontally sliding accordion or folding assemblies fabricated for use as walls and tested as wall assemblies in accordance with ASTM E119, Standard Test Methods for Fire Tests of Building Construction and Materials. A.1.1.4 The fire performance evaluation of these assemblies is tested in accordance with ASTM E119, Standard Test Methods for Fire Tests of Building Construction and Materials, for horizontal access doors; NFPA 252, Standard Methods of Fire Tests of Door Assemblies, for fire doors and shutters; NFPA 257, Standard on Fire Test for Window and Glass Block Assemblies, for fire windows and glass block; and NFPA 288, Standard Methods of Fire Tests of Horizontal Fire Door Assemblies Installed in Horizontal Fire Resistance–Rated Assemblies, for doors in horizontal fire-rated assemblies. It is not the intent of this standard to establish the degree of protection required or to constitute the approval of any product. These are determined by the AHJ.
