Fire behaviour of a vinyl based lining material with and without anti-corrosion painting has been evaluated through 35 and 50kW/m2 cone calorimeter tests. The minimum heat flux requited for surface ignition was estimated. The data were compared by those provided by a revised Kokkala-Thomas’s classification index prediction model, the Östman-Tsantaridis empirical linear regression model and the Hansen-Hovde multiple discriminant function analysis (MDA). All results collected allowed to predict the material flashover time and to classify the lining material. The results illustrate some differences in the classification of the material due to different approaches of the models used.
