Operation Breakthrough: Fire Endurance Test of a Mechanical/Electrical Core Assembly for Use in Multifamily Housing. (Test No. 503).

摘要

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)
