Standard Test Method for Determining the Fire-Test Response Characteristics of a Building Spandrel-Panel Assembly Due to External Spread of Fire
SIGNIFICANCE AND USE
5.1 This test method provides for the following measurements and evaluations:
5.1.1 Ability of the spandrel-panel assembly to resist the passage of flames or hot gases sufficient to ignite a cotton pad, or be visible to an observer.
5.1.2 Transmission of heat through, and above, the spandrel-panel assembly using heat flux and unexposed surface temperature measurements.
5.2 This test method does not provide the following:
5.2.1 This test method does not evaluate the fire propagation characteristics of exterior nonload-bearing wall assemblies containing combustible components, or flame spread over the test assembly.
5.2.2 This test method does not evaluate the fire-test-response characteristics of the perimeter joint protection between the floor assembly and the exterior wall assembly. This is covered in Test Method E2307.
5.2.3 Evaluation of the degree to which the spandrel-panel assembly contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion,
5.2.4 Measurement of the degree of control or limitation of the passage of smoke or products of combustion through the spandrel-panel assembly,
5.2.5 Measurement of flame spread over the surface of the spandrel-panel assembly or exterior wall assembly,
5.2.6 Durability of the test specimen under actual service conditions, including the effects of cycled temperature,
5.2.7 Effects of loads (for example, wind, seismic, etc.) on the spandrel-panel assembly established by this test method,
5.2.8 Movement capabilities of the test specimen,
5.2.9 Other attributes of the test specimen, such as wear resistance, chemical resistance, air infiltration, water-tightness, and so forth, and
5.2.10 Lateral spread of flame from the compartment of fire origin to adjacent spaces.
5.3 In this test method, the test specimens are subjected to one or more specific test conditions. When different test conditions are substituted or the end-use conditions are changed,...
SCOPE
1.1 This test method evaluates the fire-test response characteristics of a spandrel-panel assembly spanning the intersection of a floor assembly.
1.2 This test method is used to assess the spandrel-panel assembly’s ability to impede spread of fire to the interior of the room or the story immediately above it via fire spread from the exterior of a building, and provide a quantitative measure of the fire hazard in terms of an I-Rating, T-Rating, and F-Rating from a specified set of fire conditions involving specific materials, products, or assemblies.
1.3 This test evaluates the performance of the portions of the exterior wall installed between vertically adjacent window openings in multi-story buildings.
1.4 This test method addresses the potential for fire spread to a single story immediately above the room of fire origin.
1.5 The test method simulates a fire in a post-flashover condition in a compartment that is venting to the exterior through a window opening.
1.6 The fire exposure conditions within the test room are those specified by this test method for the first 30 min of exposure and then conform to Test Methods E119 time-temperature curve for the remainder of the test. The fire exposure on the exterior surface of the test specimen comprises both the exposure from the fire plume exiting the window opening of the test room and the exterior burner, although the fire exposure on the exterior surface of the test assembly is not equivalent to that of Test Methods E119.
1.7 This test method specifies the heating conditions, methods of test, and criteria for evaluation of a building’s spandrel-panel assembly. Specimens are not tested using any super-imposed axial load.
1.8 Test results establish the performance of the spandrel-panel assembly during the fire-exposure period and shall not be construed as having determined the suitability of a spandrel-panel assembly for use after that exposure.

INTRODUCTION
This standard test method evaluates the ability of the spandrel-panel assembly in an exterior wall
assembly, with or without glazing, to impede the spread of fire to the interior of the room or the story
immediately above it via fire spread from the exterior of a building. A building spandrel-panel
assembly includes the exterior wall spandrel-panel assembly and any glazing. The spandrel-panel
assembly is a unique building construction detail not addressed by other fire test methods.
Abuilding’s spandrel-panel assembly impedes the vertical spread of fire from the floor of origin to
the floor immediately above it, via an exterior fire exposure.
This test method describes criteria used to determine the fire performance of spandrel-panel
assemblies when subjected to standard fire exposure conditions. This test method is intended to
simulate a possible fire exposure due to a post flashover compartment fire venting through an opening,
onto the exterior surface of a spandrel-panel assembly.
