Abstract: In this paper, 11 kinds of commonly used floor are selected as the research objects. The ignition time, heat release rate, fire performance index, total heat release, effective heat of combustion and carbon monoxide generation were studied by using the cone calorimeter. The floor whose fire safety rated from high to low are chestnut, Pometia spp, scholartree, xylosma, white oak, elm, chipboard, medium density fiberboard, high density fiberboard, maple and phyllostachys pubescens. The combustion of the sample can be divided into 4 stages and they are first violent combustion stage, first combustion attenuation stage, second violent combustion stage and second combustion attenuation stage. All samples have similar effective combustion heat and carbon monoxide generation and they are 12 MJ/kg and 17×10-6.

Key words: cone calorimeter, floor, heat release rate, effective combustion heat, carbon monoxide generation
