摘要

As a part of the evaluation of a housing system proposed under Operation Breakthrough a standard fire endurance test was performed on a double wall assembly comprising a load-bearing interdwelling (party) wall for single family attached housing. The test method was in accordance with the requirements of ASTM E 119,and the applied load was 700pounds per linear foot (plf) per wall. The test results are valid only for walls of similar construction loaded at or below the stress level developed by this loading. The double wall,representative of an interdwelling (party wall) separation,was made up of two identical parallel panels from two adjacent modules separated by a 2-1/4in. air space. Each wall assembly contained glass fiber-reinforced polyester (GRP) sheet faces,glued to a corrugated GRP stiffener core. The GRP core members were painted with an intumescent type fire retardant paint and the core spaces were filled with mineral wool insulation.
