From page 228...
... Delaying this transition results in longer time for evacuation. Should this determination hold for future aircraft, then the Federal Aviation Administration goal of a 50 percent reduction in fire deaths could be achieved by using materials 228
From page 229...
... This can be measured using a device such as the Cone Calorimeter. For low heat release rates, the oxygen depletion may be too small, and an alternative measure based on, for example, CO/CO2 yield may be necessary.
From page 230...
... Should a suppression system not be installed or should it not work, this would require palette containment materials and cabin isolation materials of extraordinary fire resistance. Fortunately, the air leakage into the cargo hold could be made quite small, limiting the burning rate of the combustibles.
From page 231...
... However, research on thermogravimetry and differential scanning calorimetry coupled with mass spectroscopy is investigating the relationship between rate of heat release and ignition behavior. Participants foresaw a critical advance in the characterization of a material's fire contribution when such an appraisal can be based on the molecular chemistry and thermal embodiment of the product.
From page 232...
... Develop a validated two-dimensional or three-dimensional mode} of the evolution of habitability of the cabin environment to identify key materials parameters. Develop an understanding of flame spread in a vitiated upper layer and its impact on ignition of fire-hardened seats and wall panels, as well as of clothing and carry on items.
