7.10 Clearances for honzontal slide-type elevator doors shall be as follows: with a minus 1/8 inch (3.2 mm) tolerance — 3/8 inch (9.5 mm) between the door and wall surfaces, 3)8 inch (9.5 mm) between mullisechon door panels, and 3)8 inch (9.5 mm) from the bottom of a panel to the sill. Multisection door panels shall overlap 3)4 inch (19.1 mm). Door panels shall overlap the wall opening 3/4 inch (19.1 mm) at sides and top.
7.11 Door frames shall be evaluated when mounted so as to have the doors open either away from or into the furnace chamber, at the discretion of the testing authority, to obtain representative Information on the performance of the construction under test.
7.12 Surface-mounted hardware (fire-exit devices) for use on fire doors shall be evaluated by being installed on one door assembly swinging into the furnace chamber and another door assembly swinging away from the furnace chamber.
7.13 Door frame wall anchors, when used, shall be intended for the wall or partition construction,
CONDUCT OF TESTS
8 Supporting Construction
Revised 8 e4tective February 16. 2018
8.1 Wall construction materials shall possess the strength to retain the assembly securely in position throughout the Fire Endurance Test, Section 9, and the Hose Stream Test, Section 10.
9 Fire Endurance Test
9,1 The pressure in the furnace chamber is to be 0 ±0.01 inches of water at the top of the door.
9.2 The test is to be continued until the exposure period of the specified classification or rating is reached unless the conditions of acceptance set forth in Sections 12 and 13 are exceeded in a shorter penod.
10 Hose Stream Test
10.1 Immediately alter to within 3 minutes from the termination of the fire endurance test, the test assembly is to start to be subjected to the impact, erosion, and cooling effects of a hose stream directed first at the bottom center of the assembly and then at all parts of the exposed surface. The hose stream is to be applied, with a smooth steady movement of the hose at a rate to ensure that all parts of the test assembly are impacted by the hose stream. When all parts of the test assembly have been impacted by the hose stream, the application pattern Is to be reversed. See Appendix C for a description of the pattern.
10.2 Deliver the hose stream through a 2-1/2-inch (64.5-mm) hose discharging through a National Standard Playpipe 01 corresponding size equipped with a 1-1/8-inch (28.6-mm) discharge tip of the standard-taper, smooth-bore pattern without shoulder at the orifice. The minimum water pressure at the base of the nozzle and the minimum duration of application in seconds per square foot (s/m2) of exposed area is to be as prescribed in Table 10.1.
CONDITIONS OF ACCEPTANCE 12 General
12.1 A door assembly shall be considered as rneebng the requirements for intended performance when it remains in the opening during the fire endurance test and hose-stream test within the following limitations.
12.2 The lep edges of horizontal, slide-type passenger elevator doors, as defined in the Safety Code for Elevators and Escalators, ANSI’ASME A17.1CSA B44, including the lap edges of multisection doors, shall not move from the wall or adjacent panel surfaces resulting in a separation of more than 2-718 inches (73.0 mm) during the entire classification period, or immediately following the hose stream test, The meeting edges of center-parting elevator door assemblies, for a fire and hose stream exposure of 1-112 hours or less. shall not move apart more than 1-1,4 inches (31.8 mm) as measured in any horizontal plane during the entire classification period or immediately following the hose stream test.
12.3 Doors mounted in guides shall not release from guides and guides shall not loosen such that passage of flames occurs.
12.4 The test assembly shall withstand the Fire Endurance Test. Section 9, and Hose-Stream Test, Section 10, without developing openings anywhere through the assembly.
Exception No. 1: Dislodg,ng of small portions of glass during the hose stream, as specified in 14.6, is permitted.
Exception No. 2: Separation between meeting edges of pairs of doors within the limits specified ie 12.2, 13.2.3, 13.2.4. 13.3.5, and 13.3.6 is permitted.
Exception No. 3: An opening between the bottom edge of a door and sill within the limits specified in 7.7
— 7.10, 13.3.3. and 13.3,7 is permitted.
12.5 For the purpose of the requirement of 12.4, an opening is defined as a through-hole in the assembly that is seen from the unexposed side when viewed from the direction perpendicular to the plane of the assembly at the location of the suspected opening.
