Abstract

The ISO room corner test is used for classification of surface materials in a number of countries, and as the reference scenario test for the new European single burning item test, its importance increases even more. Time to flashover may be regarded the most important result from the room corner test. In this paper we describe three different calculation models for predicting in which period of testing time flashover in the room corner test will occur. The predictions are all based on test results from the cone calorimeter. The models are a modified version of the Wickstrom/Goransson model, the model by Ostman/Tsantaridis and a model based on multivariate statistical analysis. The three models were applied to a data set containing test results from 57 different products. We found that the modified Wickstrom/Goransson model and the statistical model generally calculated time to flashover with high precision. The Ostman/Tsantaridis model was excellent in prediction of time to flashover within 10 min of testing time, but performed poorer for time to flashover above 10 min. Based on these analyses, a simple, but efficient method for predicting the interval of time when flashover occurs is suggested.
