The effects of geometry and ignition mode on ignition times obtained using a cone calorimeter and ISO ignitability apparatus

Abstract

Abstract Three timber‐based materials were investigated by subjecting them to a constant uniform heat flux in the range 20–70 kW m −2 using a Cone Calorimeter and the ISO Ignitability Apparatus. The specimens were examined in the vertical and horizontal orientations in the Cone Calorimeter using gas flame pilot, spark pilot and spontaneous methods of ignition. They were also studied using the ISO Ignitability Apparatus in the normal and inverted horizontal orientations using gas flame pilot and spontaneous methods of ignition. The results obtained are compared by specimen, orientation and mode of ignition.
