10、009 (Title Page Reprinted: December 10, 2013) HISTORICAL NOTE The title Tin-Clad Fire Doors is historically related to two- or three-ply wooden core construction covered with sheet steel as thin as 0.01 in (0.25 mm) coated with roong grade terne plate having a composition of 20 percent tin and 80 pe
11、rcent lead. More recently the title has been retained as also applying to identical construction except for the substitution of zinc coating for terne coating with the provision that zinc coated metal should be painted with a good grade of corrosion resisting paint prior to shipment. The maximum met
12、al section (plate) size of 14 by 20 in (356 by 508 mm) is dictated by the original concept that the extremely thin base metal was to be secured only by nails having their heads covered by fold-over laps and the need for the resultant seams to be spaced sufficiently close as to prevent bulging or sur
13、face distortions. The original title has been retained to relate to the basic concept for this class of construction in trade usage, as is so referenced in several national and other building codes, as well as in the current edition of the Standard for Fire Doors and Other Opening Protectives, NFPA
14、No. 80. This edition has been edited to delete use of the word plate as the present trade usage of this term relates to hot-rolled steel having a thickness of at least 0.230 in (5.8 mm). 1 UL 10A Standard for Tin-Clad Fire Doors Previous numbered and unnumbered editions of standards covering this ma

26、f tin-clad re doors which when so fabricated have demonstrated in re tests conducted in accordance with the Standard for Fire Tests of Door Assemblies, UL 10B, re performance properties which warrant their use as re doors having a rating of 3, 1-1/2, or 3/4 hour. 1.2 The doors covered by these requi
27、rements are intended to be mounted with re door hardware of the following types: a) Sliding hardware and b) Swinging hardware. 1.3 A tin-clad re door employing materials and/or having forms of construction differing from those detailed herein are to be examined according to the intent of these requi
28、rements and shall be tested for re performance in accordance with the Standard for Fire Tests of Door Assemblies, UL 10B. If when so tested, it is determined that the re door complies with the Conditions of Acceptance of this test method it is to be classied as a tin-clad re door having the applicab
29、le re performance rating of 3, 1-1/2, or 3/4 hour. 1.4 Doors complying with these requirements are classied as to temperature rise on the unexposed side to 250F (139C) maximum at the end of the rst 30 minutes of exposure to re; or have no classication referencing temperature rise. See Table 2.1. 1.5
30、 A door conforming to these specications consists of a core made up of layers of boards nailed to each other, encased in terne or zinc coated steel in the form of sections jointed together at their edges and nailed through the seams to the core. 1.6 Requirements for the location and time rating are
31、contained in codes, such as the International Building Code published by the International Code Council and the Building Construction and Safety Code, NFPA 5000. The method of installation required for re doors is not included in these codes. Requirements for the details for the installation of tin-
32、clad re doors, including the requirements for vent holes and glazing are included in the Standard for Fire Doors and Other Opening Protectives, NFPA 80. 1.7 These requirements do not cover electrical, mechanical, or other features which relate to the risk of re or accident beyond the scope of these
33、requirements.

34、pertains only to the maximum size of the opening. Doors limited in size by this table fall into two categories: a) Swinging doors intended to be installed within an opening and b) All sliding doors and those swinging doors intended for surface mounting outside of the opening. Swinging doors in (a) a
35、re limited in size to the maximum dimensions specied for the opening. Doors in (b) must be larger than the maximum opening dimensions to provide the minimum 4 in (102 mm) lap at each side and the top of the door as required by the Standard for Fire Doors and Other Opening Protectives, ANSI/NFPA 80.
36、Doors exceeding these two basic dimension considerations are termed Oversize, the design and construction of which are not necessarily fully covered in these requirements. 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or a
37、pproximate information. 2.2.2 The tolerance for all dimensions shall be as specied with the dimension. Where no tolerance is shown, the tolerances specied in Appendix A shall apply. See Appendix A for specications. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in
38、 the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.
