Abstract : The flammability and ignition properties of JP-5 from alternate sources were studied. The samples which were investigated included one derived from tar sands, one from shale oil, and five from coal. The tar-sand, shale-oil, and one of the coal samples had flash points which were below that of the 140 F specification requirement. The remaining fuels from coal had flash points which were higher than specification requirements, and also higher than those of the usual run petroleum JP-5. Flammability indices and flammability index-temperature relationships of the alternate fuels were found to differ somewhat from that of the petroleum fuels. Autoignition temperatures of the alternate fuels were similar to that of petroleum-derived fuels. In general, the flammabability properties of the JP-5 from alternate sources were not significantly different from that of JP-5 from petroleum. (Author)
