Fire Endurance Tests of Steel Sandwich Panel Exterior Wall and Roof/Ceiling Constructions.

摘要

As part 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 paper honeycomb core with sheet steel facings. 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. The fire endurances of the wall assembly and the roof/ceiling were noted.
