Differences between Jet A and Jet A-1
Jet A specification fuel has been used in the United States since the 1950s and is only available in the United States, whereas Jet A-1 is the standard specification fuel used in the rest of the world. Both Jet A and Jet A-1 have a relatively high flash point of 38 °C (100 °F), with an of 210 °C (410 °F). This means that the fuel is safer to handle than traditional avgas.
The primary differences between Jet A and Jet A-1 are the higher freezing point of Jet A (−40 °C vs −47 °C for Jet A-1), and the mandatory requirement for the addition of an anti-static additive to Jet A-1.
Like Jet A-1, Jet A can be identified in trucks and storage facilities by the UN number 1863 Hazardous Material placards.[2] Jet A trucks, storage tanks, and pipes that carry Jet A are marked with a black sticker with a white "Jet A" written over it, next to another black stripe.
The annual U.S. usage of jet fuel was 20.2 billion gallons (77 billion litres) in 2009.[3]
[edit] Typical physical properties for Jet A and Jet A-1
Jet A-1 Fuel must meet the specification for DEF STAN 91-91 (Jet A-1), ASTM specification D1655 (Jet A-1) and IATA Guidance Material (Kerosine Type), NATO Code F-35.
Jet A Fuel must reach ASTM specification D1655 (Jet A) [4]
