- Abstract
- A simulation model is implemented in order to predict the performance of materials in the ISO 9705 Room-Corner Test. These materials were tested by the L S Fire Laboratories of Italy, and the data they provided is analyzed in this report. A method was established to define material properties including the heat of combustion, heat of gasification, thermal inertia, ignition temperature and the total energy per unit area. These methods were developed from refinements in the theoretical model of ignition and in resolving time dependent effects in the Cone Calorimeter. The materials examined consist of some of the worst behaving since they melt, drip, expand and de-laminate from the wall and ceiling configuration of the room-corner test. Corrections have been included in the simulation modeling to account for these effects. The correction involves reducing the total energy per unit area content of the material to accordingly reduce its contribution as a wall-ceiling oriented element. An empirical correlation based on a linearized upward flame spread model is shown to provide very good correlation to the flashover time in the full-scale ISO test. **NIST-GCR-98-753 contains the discussion of the data developed for the analysis. The title of the report is Properties and the Prediction of the Energy Release Rate of Materials in the ISO 9705 Room-Corner Test by S. E. Dillon, W. H. Kim and J. G. Quintiere.**
