Jet A1 (Rotterdam)

JET A-1 is an aviation fuel formerly known as kerosene which is suitable for most jet aircraft.

It meets stringent international requirements, particularly those of the latest versions of the AFQRJOS, the British DEF STAN 91-91 standard, the ASTM D1655 standard, and the NATO F-35 specification.

It has a minimum flashpoint of 38C and a maximum freezing point of -47C.

JET A-1 is the principal fuel used for jet turbine engines. It is also used in general aviation for compatible diesel engine planes.

Jet fuel or aviation turbine fuel (ATF) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colourless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance.

Jet fuel is a mixture of a large number of different hydrocarbons. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, the freezing point or smoke point. Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 (carbon atoms per molecule); wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15.
