Abstract

Six room/comer tests of common wall linings were conducted with gypsum-lined ceiling exposed to propane burning at 100 kW for 10 min followed by 300 kW for 10 min. This test protocol is an option provided by ISO 9705. The flashover event occurred at 1,000 kW rate of heat release within several seconds of observing flames out the doorway. The time to flashover of the fire-retardant-treated polyurethane foam was 10.5 rein, which contrasts with no flashover for some melting materials exposed to propane burning at 40 and 160 kW. The time to flashover for all the wood materials tested ranged widely from 3 to 15 rein, with the longest times for fire retardant-treated plywoods. This result provides effective indications of fire performance for common materials. A correlation between time to flashover with flame spread index from ASTM E84 along with thermophysical properties measured in the cone calorimeter is presented.
