In a program of evaluation of various housing systems proposed under Operation BREAKTHROUGH, a fire endurance test was performed at the National Bureau of Standards on a roof/ceiling assembly consisting of a paper honeycomb structural core surfaced both sides with glass-fabric impregnated with polyester resin and outer layers of gypsum board. The test method was generally in accordance with the requirements of ASTM E 119 for loadbearing roof assemblies. The applied load was 15.9 psf and the test results are valid only for roof/ceilings of similar construction loaded at or below the stress level developed by this loading. Under a loading equivalent to the application of 20 psf on a 12 ft. span, failure time by flame-through was noted.
