- Abstract
- As apart of the evaluation of a housing system proposed under Operation BREAKTHROUGH, fire endurance tests were performed at the National Bureau of Standards on an exterior wall assembly and a roof/ceiling assembly. Both constructions were assemblies of sandwich panels composed of a paper honeycomb core with sheet steel facings. The test method was in accordance with the requirements of ASTM E 119, Standard Method of Fire Tests of Building Construction and Materials, for loadbearing structures. The applied live load was 237 pounds per linear foot (p1f) for the wall assembly and 28.6 pounds per square foot (psf) on a 13 ft 5 in. span for the roof/ceiling assembly. The results of these tests are valid only for walls and roof/ceilings of such constructions described in this report and loaded at or below the stress levels developed by these loadings.
