Standard Test Method for Determining Fire Penetration of Exterior Wall Assemblies Using a Direct Flame Impingement Exposure

Importancia y uso:

5.1 The test method described herein measures the ability of the exterior wall covering material or system to resist fire penetration from the exterior to the unexposed side of the wall assembly under the specified conditions of exposure.

5.2 Representative joints and other characteristics of an assembly shall be included in a test specimen when these details are representative of the construction of the end-use product(s).

5.3 This test method is applicable to end-use product(s) not having an ideally planar external surface.

5.4 The overall performance of the test specimen is visually documented by full-color photographic records. Video recording of the complete fire test is an acceptable alternative to the photographic record. Infrared photography of the unexposed side of the test wall can be used to identify areas of increasing temperatures or persisting hot spots.

5.5 In this procedure, the specimens are subjected to a specific set of laboratory fire test exposure conditions. If different test conditions are substituted or the anticipated end-use conditions are changed, it is not known whether it is possible by use of this test to predict changes in the performance characteristics measured. Therefore, the results are strictly valid only for the fire test exposure conditions described in this procedure.
