Abstract
In this report a first attempt is made to predict the flame spread of cables in full scale tests by means of cone-calorimeter test results. The predictions are based on the state of the art in the field of wall- and ceiling linigs, floor coverings and furniture. Not only correlations between small scale and full scale are performed but also an analytical and numerical model is developed and evaluated. Before all materials were tested in the cone calorimeter, a limited set was used to investigate the reliability of the small scale test procedure. The chosen test procedure was based on a literature review. The procedure was robust enough to be used for the set up of a cone calorimeter data base on 10 different type of cables. Full scale test data according to the UL 1666 test and the IEC 332.3 test apparatus were obtained from a previous NORDTEST project. A correlation study as well as analytical and numerical models were developed and showed an acceptable level of agreement taking into account the assumptions made to develop them. Future improvements for the models are suggested which can be valuable in forthcoming research on flame spread of cables.
