Abstract
An evaluation of the current materials in class 5A spaces was conducted to ensure the fire load specified in US Coast Guard regulation 46 CFR subchapter K of 5 kg/m2 does not cause life endangerment. Cone calorimeter testing of seat foam and fabric determined time to ignition dependant on heat flux. Total heat release rate was calculated through full scale testing of seats common in class 5A spaces. A Fire Dynamic Simulator (FDS) model of a class 5A space with data from previous tests was then used to calculate heat transfer into ceiling to determine if flashover occurs and if the exposed upper deck surface temperature reaches a critical 232¢ª C value when passenger safety is jeopardized due to structural integrity loss of aluminum. Theoretical calculations verified FDS thermal and physical properties with temperatures remaining at a level below the critical value.
