Standard Test Method for Determining the Fire-Test Response Characteristics of a Building Spandrel-Panel Assembly Due to External Spread of Fire

Importancia y uso:

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, it is not always possible by, or from, this test method to predict changes to the characteristics measured.

5.4 This test method is not intended to be used as the only test method in the selection of a spandrel-panel assembly. It is not intended as a specification for all attributes required by a spandrel-panel assembly, or any of its individual components, in order for a spandrel-panel assembly to be used in a particular application.
