Heat Release Testing of Stacked Chairs: Analysis of Repeatability in a Single Laboratory

摘要

Fire testing of furniture has been focus of much attention in 1990s, particularly in terms of the heat it releases in real-scale fires. One aspect that has received insufficient attention is the case of stacked chairs, often found in places of assembly. Early data have shown that the fire hazard resulting from burning a stack of chairs is often much higher than would have been expected simply from the combined hazard of the individual chairs. A test has been designed, ASTME1822, in which the flames from a propane gas burner (at 12 l min~-1) are applied to a vertical stack of 5 chairs For 80 s, and the important fire properties measured.
