Comprehensive and innovative measurements will be conducted in a series of full-scale underventilated room fires. Detailed measurements accounting for carbon in every possible form (i.e., fuel, soot, intermediate, and complete products of combustion) will be performed. Comprehensive data sets of this type have not been previously reported for full-scale enclosure fires. The chemical data will be augmented by temperature and velocity data to provide a complete picture of the physics and chemical structure of the environment within the fire enclosure. Measurements will be completed for a variety of fuel types and configurations, and a fully annotated data base will be made publically available.
