  2.2. Gypsum board for mounting around the window once it is installed; 2.3. Pieces of gypsum cut into narrow strips for use as trim around the window; 2.4. Caulk to be used as per the window manufacturer's instructions. 3. Wall assembly. A noncombustible wall shall be used with a manufacturer or code-specified opening for the particular window. Install window in framed rough opening following manufacturer guidelines. Apply manufacturer-recommended caulk to nailing flange prior to installation. Use narrow strips of gypsum board as trim around window, covering the nail flange of the window. Any type of framing material may be tested. 3.1. Fit the window test assembly into the rear wall of the Wall Assembly Test Module, sealing all edges, including the soffit-to-wall joint. Ceramic wool or comparable material shall be used for sealing.

  12-7A-2.7 Conduct of tests.

  1. Burner output verification. Without the window in place, set the burner for 150 kW output. Conduct a verification run of 3 minutes to assure the heat release rate, and then turn off the burner.

  2. Test. Place the burner against the wall assembly at the center. Ignite the burner at the 150 kW output and control during the test for constant and uniform output. Optional radiometers can be placed behind the Wall Assembly Test Module to measure heat flux through the window glass.

  3. Duration and observations. The test shall be continued until flame-through occurs at the window. Flame-through can occur at the glass (glazing) and/or in the frame. At this point, the burner shall be extinguished and the assembly monitored for sustained combustion. Note the time elapsed and location of penetration if it occurs.

  4. Report. Report a description of the window unit, including the types of frames, cladding and panes being tested and details of the installation. Record when and how the glass breaks or flame-through occurs in the framing materials or sash, and/or

  if the framing material deforms or otherwise suffers a loss of integrity such that the glass cannot be held in place, and a record of the time at which any of these events occur.

  12-7A-2.8 Conditions of Acceptance.

  1. Duration of direct flame exposure. To pass this test standard, the window and window assembly shall withstand 8 minutes of direct flame exposure with the absence of flame penetration through the window frame or pane, or structural failure of the window frame or pane.
  2. Flame penetration or structural failure. Flame penetration or structural failure of the flame or pane anytime during the test constitutes failure of this test standard.

  SCOPE

  Sec. 12-10-300.

  (a) Exit door hardware. These requirements and methods of test apply to releasing devices actuated by a crossbar for outwardopening doors intended for use on exit doors.

  (b) Fire-exit hardware. Releasing devices intended for use on doors bearing a fire-retardant classification shall also conform to the construction standards and performance tests specified in Fire Door Assembly Tests, SFM 12-7-4, Section 12-7-400.

  (c) Listing by approved listing agency. Listing by an approved listing agency shall not be construed as necessarily indicating compliance in all respects with the requirements of these Construction Standards and Performance Tests for Emergency Exit and Panic Hardware. The test report of the listing agency may be filed for review and after evaluation, if it is found to provide evidence of conformance, the releasing device assembly may be recognized for approval and listing.

  INSTRUCTIONS

  Sec. 12-10-301. Approved installation instructions shall be provided by the manufacturer. Instructions shall be illustrated and shall include directions and information adequate for obtaining proper and safe installation of the equipment.

  DESIGN

  Sec. 12-10-302.

  (a) Releasing pressure. Exit panic hardware mechanisms shall be designed to release the door latch or latches when pressure not to exceed 15 pounds is applied at any point along the cross-bar perpendicular to the door in the direction of exit travel. The cross-bar shall extend across not less than one-half the width of the door.

  (b) Locking device. A locking device employed as part of the mechanism shall not prevent release of the door latch or latches when pressure of not to exceed 15 pounds is applied to the cross-bar in the direction of exit travel.

  (c) Dead locking bolt. A dead locking bolt shall not be provided as a part of the mechanism unless it is released and retracted, and does not prevent release of the door latch or latches, or release of the door to swing outward when pressure not to exceed 15 pounds is applied to the cross-bar in the direction of exit travel.

  (d) Cross bar. The ends of the cross-bar shall be curved, guarded or otherwise designed to prevent catching on the clothing of persons during egress.

• CRSC § 12-7 Medium relevance — show source text

  (e) Furnace pressure. The pressure in the furnace chamber during the fire test shall be maintained as nearly equal to atmospheric pressure as possible. Horizontal furnaces may be operated at a slight negative pressure sufficient to reduce haze permitting visual observation. Furnace stacks shall be equipped with dampers to facilitate maintenance of furnace pressure.

  CORRELATION

  Sec. 12-7-305. Tests of specific assemblies of materials shall be conducted for correlation (or correlation factor) of furnace exposure by comparison with tests of identical assemblies and materials conducted in furnaces of “Approved Listing Agencies” which furnaces are deemed as conforming to the design and operating requirements of this standard.

  Correlation tests of wall furnaces shall include tests of two assemblies, one combustible and one noncombustible.

  Correlation tests of horizontal furnaces dependent on intended test specimens shall include at least one test for each type of assembly such as combustible ceiling-floor assembly, noncombustible assembly having a high thermal capacity floor for heat dissipation, noncombustible assembly having an insulating concrete floor or other type of design.

  Comparison of test results shall provide evidence of equivalent exposure based on transmitted temperatures on the unexposed side, on structural framing members, on the underside of floor or roof decks, and in the plenum space.

  12-7-4 FIRE-RESISTIVE STANDARDS

  FIRE DOOR ASSEMBLY TESTS

  STANDARD 12-7-4

  STATE FIRE MARSHAL

  SCOPE

  Sec. 12-7-400.

  (a) Application. These methods of fire tests are applicable to door assemblies of various materials and types of construction for use in wall openings to retard the passage of fire (flame, heat and smoke).

  (b) Performance. Tests made in conformity with these test methods will register performance during the test exposure, but such tests shall not be construed as determining suitability for use after exposure to fire.

  (c) Suitability of assemblies. It is the intent that tests made in conformity with these test methods will develop data to enable enforcing agencies to determine the suitability of door assemblies for use in locations where fire resistance of a specified duration is required.

  FIRE TESTING FURNACES AND CONTROL

  Sec. 12-7-401.

  (a) Furnaces. Fire testing furnaces and their control shall conform to SFM 12-7-3, Fire Testing Furnaces, Section 12-7-301 (a), Vertical Large-scale Wall Furnaces.
