Fire Endurance Test of a Conventional Plywood Faced Wood Stud Exterior Wall Containing Fiberglass Insulation Batts.

摘要

A fire endurance test was performed at the National Bureau of Standards on a conventional wood-stud wall with plywood facings and fiberglass insulation. The test method was generally in accordance with the requirements of ASTM E 119,Fire Tests of Building Construction and Materials,for a loadbearing wall. The applied load of 600 plf was representative of the design and the results are valid only for walls of similar construction loaded at or below the stress level developed by this loading. The fire endurance of the wall assembly,determined by the time to flame through to the unexposed surface,was 15minutes 45seconds. Failure to sustain the applied load occurred at 26minutes 20seconds.
