ABSTRACT

In 1992, Factory Mutual Research Corporation (FMRC) and the National Research Council Canada (NRCC) initiated a joint research project on upward flame spread in which NRCC set-up and conducted upward flame spread tests using a large-scale radiant panel facility. The test procedure, developed as part of the joint research project, is described and the results obtained using plywood specimens are discussed. The University of Kentucky team was invited to join this project and to provide their expertise on automated infrared temperature measurements. The identical materials were also tested using a bench-scale fire test apparatus to provide input for the FMRC upward Flame Spread and Growth (FSG) model. An overview of the FSG model and the small-scale tests is provided in this paper. Simulations for both the small-scale and full-scale tests with plywood specimens are provided and comparisons made with the experimental results
