Jet A specification Fuel has been used in the United States since the 1950s and is usually not available outside the United States and a few Canadian airports such as Toronto and Vancouver. Jet A has a flash point higher than 38 °C (100 °F), with an auto-ignition temperature of 210 °C (410 °F). The primary difference with Jet A-1 is the higher freezing point of Jet A of −40 °C (−40 °F). Jet A trucks, storage tanks, and plumbing that carry Jet A are marked with a black sticker with "Jet A" in white printed on it, adjacent to another black stripe. Jet A fuel must reach ASTM specification D1655 (Jet A).^[1]

The nominal Jet-A Fuel was evaluated by two-dimensional gas chromatography, providing the HC class distribution with all four major classes of HCs scattered over multiple Carbon numbers (Picture). However, if the Aromatic concentration was too low, the seals in the engine and aircraft would leak.^[2]
