To evaluate the performance of discharged foam agents used to protect structures from heat and fire damages, the thermal characteristics of fire-extinguishment foams were experimentally investigated.Especially, two different parameters of a spray nozzle, that is, the number of air holes and the orifice diameter, were considered.A simple repeatable test for fire-extinguishment foams subjected to fire radiation was performed.Experimental results showed that the expansion ratio of the discharged foam with the small orifice throat (do=9.5 mm) and opened air hole (Nh=9) was large.
