Cone calorimeter tests were conducted to investigate the flammability of glass-reinforced plastics (GRP) panels. The results
gained from these bench scale tests were used to predict the time to flashover in the ISO 9705 room, which was partly covered
by GRP panels. Östman and Tsantaridis’ empirical linear regression model and multiple discriminant function analysis (MDA)
were used in the prediction. Three room-scale GRP fire tests were conducted in ISO 9705 room and the results were compared
with the prediction.
