This report describes new full-scale compartment fire experiments, which include localmeasurements of temperature, heat flux and species composition, and global measurements ofheat release rate and mass burning rate. The measurements are unique to the compartment fireliterature. By design, the experiments provided a comprehensive and quantitative assessment ofmajor and minor carbonaceous gaseous species and soot at two locations in the upper layer offire in a full scale ISO 9705 room .
Fire protection engineers, fire researchers, regulatory authorities, fire service and lawenforcement personnel use fire models (such as the NIST Fire Dynamics Simulator, FDS) fordesign and analysis of fire safety features in buildings and for post-fire reconstruction andforensic applications. Fire field models have historically showed limited ability to accuratelyand reliably predict the thermal conditions and chemical species in underventilated compartmentfires. Formal validation efforts have shown that for well ventilated compartment fires, with theexception perhaps of soot, field models do quite well in predicting temperature and species whenexperimental uncertainty is accounted for. Inaccurate predictions of incomplete burning and sootlevels impact calculations of radiative heat transfer, burning rates, and estimates of humantenability. High-quality (relatively low, quantified uncertainty) measurements of fire gasspecies, temperature, and soot from the interior of underventilated compartment fires are neededto guide the development and validation of improved fire field models.
