Overall Fire Safety of Cable and Wiring Materials. Part 1.
BENJAMIN/CLARKE ASSOCIATES INC KENSINGTON MD
Pagination or Media Count:
Small-scale tests for flammability are inadequate to predict fire performance in full-scale fires. Ignition resistance and flame spread measured by existing standard tests must be supplemented if overall cable fire hazard it to be assessed. Additional relevant data are provided by determining material behavior at elevated heat flux levels typical of those expected in room fires. In addition, computer-based room fire models are used to predict the full-scale conditions which cable materials may experience. This information can than be combined to provide a quantitative estimate of the contribution of cable materials to overall fire hazard. Hazard aspects include circuit integrity, structural fire spread, smoke generation and smoke toxicity. Author
