- Abstract
- As a part of the evaluation of a housing system proposed under Operation BREAKTHROUGH, a fire endurance test was performed at the National Bureau of Standards on a floor, made up of sandwich panels consisting of a paper honeycomb core with steel and plywood surfaces, supported on steel joists. The test method was generally in accordance with the requirements of ASTM E 119, Fire Tests of Building Construction and Materials, for loadbearing floor constructions. The applied live load was 40 psf and the test results are valid only for floors of similar construction loaded at or below the stress level developed by this loading. Failure occurred by flame through of the floor assembly in 8 min. 45 sec., with structrual failure (inability to sustain the applied load) flollowing immediately.
