Kerosene Colonial Grade *4 Jet Fuel JP *4: Jet fuel A*1.Jet fuel designed for
use in aircraft powered by gas-turbine engines. It is clear to
straw-colored in appearance. The most commonly used fuels for
commercial aviation are Jet A and Jet A*1 are produced to a
standardized international specification. Jet fuel is a mixture of
a large number of different hydrocarbons. The range of their sizes
is restricted by the requirements for the product, for example, the
freezing point or smoke point. Kerosene-type jet fuel has a carbon
number distribution between about 8 and *6 carbon numbers (carbon
atoms per molecule); wide-cut or naphtha-type jet fuel (including
Jet B), between about 5 and *5 carbon number. Jet A*1 is the
standard specification fuel used in the rest of the world. Jet A*1
has a flash point higher than *8 °C (**0 °F), with an autoignition
temperature of **0 °C.
