Frame Jambs. This usually consists of two vertical members side jambs and two horizontal members head and sill that hold the sash. Frames and sash are typically made of steel, aluminum, vinyl, fiberglass, wood or a combination of these materials.
The glass in a window. It may include layers of plastic as well as glass. The fixed or movable parts of the window in which the panes of glass are set. It includes two noncombustible side walls attached to a wall frame assembly, and a simulated soffit that is also noncombustible.
Natural gas, methane or propane shall be supplied to the burner through a metered control system. Burner output can be determined from HRR or calculated from the gas flow rate, temperature, and pressure. Burner location. The burner shall be positioned so that it is centered relative to the width of the wall assembly and against the wall.
The distance from the floor to the top of the burner shall be 12 inches mm. The window width cannot exceed 3 feet mm due to the limitations of the test fixture. The distance from top of the burner to bottom of window will be 8 inches mm. Note: Larger windows may be tested by expanding the size of the rear wall of the Wall Assembly Test Module. Gypsum board for mounting around the window once it is installed; 2.
Pieces of gypsum cut into narrow strips for use as trim around the window; 2. 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. 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. Without the window in place, set the burner for kW output. Conduct a verification run of 3 minutes to assure the heat release rate, and then turn off the burner.
Place the burner against the wall assembly at the center. Ignite the burner at the 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. Duration and observations. The test shall be continued until flame-through occurs at the window.
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. Report a description of the window unit, including the types of frames, cladding and panes being tested and details of the installation. 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.
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. Materials and assemblies that meet the performance criteria of this standard are acceptable for use as defined in the California Building Standards Code.
