CHARRING MATERIAL PROPERTIES

There are various methodologies available 1,2,3 for the determination of flammability properties of noncharring polymeric materials. This paper presents a demonstration, validation and extension of a distinct methodology for obtaining the flammability properties of charring materials. Australian radiata pine was used for the study wherein ignition and pyrolysis characteristics were obtained using a cone calorimeter. The deduced properties were applied for the prediction of ignition and pyrolysis histories of wood. These predictions were compared with data obtained from the cone calorimeter at different imposed heat fluxes and wood thicknesses and a close agreement was observed between the theoretical and experimental results.
