- Abstract
- An experimental program was conducted to study the thermochemical, flammability, and toxicological characteristics of JP-4 aircraft fuel, isocyanurate foams, intumescent coatings, and Fluorel. Testing methods included XP-2 chamber smoke test, ASTM D-1692, infrared photography, Bureau of Mines penetration test, and use of the Instron Environmental Chamber to measure compressive strength. Combustion and pyrolysis gases were analyzed by gas chromatography and mass spectrometry. The LD-50 test was performed on Sprague-Dawley rats housed in an environmental chamber. The isocyanurate foam, fluorel-coated foam, and the intumescent-coated foam were found to have excellent flammability and insulation characteristics, although smoke development was substantial. The LD-50 values for Sprague-Dawley rats, based on a two-week survival, were approximately 2.0 gm/ft3 for all three materials.
