Standard Test Method for Resistance to Wildfire Penetration of Eaves, Soffits and Other Projections
Importancia y uso:
5.1 The test method described herein monitors the fire characteristics and the ability of eave overhangs and other projections to resist exterior fire penetration from underneath under the specified fire exposure conditions.
5.2 Representative joints and other characteristics of the eave overhang or projection shall be included in the test specimen when these details are representative of the end-use construction.
5.3 The test method does not apply to vents or perforated materials used to enclose or cap eaves, soffits, and other projections.
Note 1: Test Methods E2912 and E2886/E2886M are methods used to test vents or perforated materials to resist direct flame impingement and flame penetration into the building.
5.4 The test method is devised for eave overhangs and other projections independent of the materials covering the building envelope.
Note 2: Heat contribution from burning materials covering the building envelope beyond the prescribed fire exposure is not considered in this test method.
5.5 The test method does not necessarily represent the expected performance of eave overhang and projections under all actual fire conditions, but it does provide a basis for comparing eave overhang and projections materials when subjected to the test procedure described herein.
5.6 In this procedure, the test specimen is subjected to specific laboratory fire test 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 conditions and construction tested.
5.7 The test method does not provide any basis for determining the fire resistance characteristics of eave overhangs or projections when exposed to a fire originating in the building.
5.8 The test method does not address interior or exterior flame spread.
