JP A-1
Jet A is the standard jet fuel type in the U.S. since the 1950s and is only available there. Jet A is similar to Jet-A1, except for its higher freezing point of ?40 ºC (100 ºF), with an auto ignition temperature of 210 ºC (410 ºF). Jet A can be identified in trucks and storage facilities by the UN number 1863 Hazardous Material placards.
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. Jet A will have a clear to straw color if it is clean and free of contamination. Water is denser than Jet A, and will collect on the bottom of a tank. Jet A storage tanks must be dumped on a regular basis to check for water contamination. It is possible for water particles to become suspended in Jet A, which can be found by performing a “Clear and Bright” test. A hazy appearance can indicate water contamination beyond the acceptable limit of 30ppm (parts per million).
