18、in re tests re-resistive properties warranting their use with two-ply and three-ply tin-clad re doors tested in accordance with the Standard for Fire Tests of Door Assemblies, UL 10B (NFPA No. 252). 1.2 Requirements for the location and time rating are contained in codes, such as the International B
19、uilding Code (IBC). The method of installation required for re doors is not included in these codes. Requirements for the details for the installation of horizontally sliding two-ply and three-ply tin-clad re doors are included in the Standard for Fire Doors and Other Opening Protectives, NFPA 80. 1
20、.3 The hardware included in these requirements is designed for mounting standard two-ply and three-ply tin-clad horizontally sliding re doors for protection of openings not exceeding the dimensions for the hourly classications indicated in Table 1.1. 1.4 These requirements do not cover automatic rel
21、easing or closing mechanisms.

25、lad re doors is to include: a) One track, length equal to twice the width of the opening plus 21 in (530 mm) drilled for wall bolts. b) Two hangers for openings 6 ft (1.8 m) and less in width; three hangers for openings wider than 6 ft (1.8 m), and bolts for attaching hangers to door. c) Two front b
26、inders for openings 8 ft (2.4 m) and less in height; three front binders for openings in excess of 8 ft (2.4 m); one rear binder and rear-binder pocket with strip for openings of 7 ft (2.1 m) and not more than 10 ft (3.1 m) in height; two rear binders and rear- binder pockets with strips for opening
27、s exceeding 10 ft (3.1 m). d) One stay roll with attachment bolts required for the form of sill used. e) One bracket for each track bolt. f) Two half-oval chang strips for back of door; two at strips for front of door opposite of half- oval strips; bolts for fastening above strips together through d
28、oor; length of strips to be 4 in (102 mm) less than width of door. Doors exceeding 8 ft (2.4 m) in height require three chang strip assemblies. A rear-binder pocket strip to be employed in lieu of the top oval chang strip on doors equipped with two rear-binder pockets. g) One strip 5 in (127 mm) les
29、s than width of door to take wear of stay roll; and wood screws for attachment. h) One wedge with screws for attachment. i) Handles with bolts and screws for attachment. j) One front bumper and one back bumper. k) Four bumper shoes and screws for attachment; each bumper shoe is made in two pieces. l

34、 5.2.1 Holes for wall bolts shall be 13/16 in (20.6 mm) in diameter and located so that a wall bolt shall be placed directly opposite each hanger when the door is closed and so that front and back bumpers can be attached to the end bolts. See Figure 5.1 for details. 5.2.2 The location of bolt holes
35、and the number and location of hangers are shown in Table 5.1 and Table 5.2. 5.2.3 The space (A) in Table 5.1 shall always be on the side of the door opening toward which the door closes. This is the lower end when the track is inclined. 5.2.4 Doors for openings in excess of 6 ft (1.8 m) in width sh
36、all require three hangers. 5.2.5 When the size of the door opening is not specied in Table 5.1 or Table 5.2, the proper interpolation shall be made for the bolt spacing in accordance with 5.2.6. 5.2.6 To determine the proper spacings for track bolt holes where the track is for an opening of a width
37、not specied in Table 5.1 or Table 5.2, add to each of the spacings (excepting dimension A given in the table) for an opening of the next smaller width in the table than that width under consideration, a value C obtained from the formula: in which: C is the correction factor in inches or mm, D is the
38、 width (in inches or mm) of opening under consideration, d is the width (in inches or mm) of opening next smaller in table, and b is the number of bolts required by Table 5.1 and Table 5.2 for track for width opening of size d.
