Abstract
Fire endurance tests were performed on two full-scale and twelve small scale wood floor constructions. The fire endurance ratings on unfinished wood joist and plywood subfloor constructions varied from 10 to 13 minutes and were mainly determined by the time to "flame through." In small-scale tests, the addition of carpeting with a hair pad delayed the time of "flame through" approximately 8 minutes. Time to "flame through" may be estimated from the thermal resistance of the construction, and may be modified by the effects of applied load or construction details such as gaps, joints, and penetrations.Citation
