This report documents a set of 9 full scale ISO 9705 room under-ventilated compartment fire experiments. The gas species composition and temperature throughout the interior of the compartment were mapped during quasi-steady burning conditions. Particular focus is placed on minor carbonaceous gas species and soot. Fire protection engineers, fire researchers, regulatory authorities, fire service and law enforcement personnel use fire field models such as the National Institute of Standards and Technology (NIST) Fire Dynamics Simulator (FDS) for design and analysis of fire safety features in buildings and for post-fire reconstruction and forensic applications.
