As part of the evaluation of a housing system proposed under Operation Breakthrough, a fire endurance test was performed on a mechanical/electrical service core assembly. The test method was generally in accordance with the requirements of ASTM E119, Fire Test of Building Construction and Materials. The test assembly was arranged to represent a two story section of a vertical mechanical/electrical core penetrating a concrete floor. The lower story was exposed to fire inside the NBS floor furnace while the upper story extended above the furnace closure. (Abstract Modified Abstract)
