Abstract : A study was made of the burning characteristics of airplane interior materials ignited inside a 640-cubic-foot cabin mockup enclosure. Test conditions were varied to investigate the effects of a number of factors on the ignition and propagation of flames within enclosures; namely, flammability ratings of the materials as obtained from standard laboratory tests; intensity, duration and type of the ignition source whether flaming or incandescent; ventilation rate as provided by different size openings into the cabin enclosure; partitioning of the cabin space by use of a fire barrier curtain; and discharge of bromotrifluoromethane into the cabin atmosphere, both at different rates and total quantities of application before and during a fire occurrence. Comparative tests conducted on flame-retardant urethane and neoprene foams showed that the flash fire hazard prevalent with the use of regular foam could be greatly reduced by replacement with these two self- extinguishing foams.
