This report concentrates on the thermal theory models for flame spread. The report shows how information on time to ignition and rate of heat release from bench-scale tests can be used to estimate time to ignition and fire growth in certain full-scale scenarios. The Cone Calorimeter is used to get bench-scale data on time to ignition and the energy release rate of a given material. The theoretical thermal models are described and a statistical package called @Risk is used to determine the values of a number of constants inherent in the models. These constants are then used in the models, allowing flame spread and energy release rate to be calculated for a number of simple full-scale scenarios, using data from the Cone Calorimeter test as input.
