Jet A-1
Jet A-1 is the standard international grade of commercial aviation turbine fuel (jet fuel).
Jet A-1 has a lower freeze point than Jet A (the grade commonly used in the US), which is better suited to high-altitude intercontinental flights, especially over polar regions.
Jet A-1 fuel must meet the following standards:
- DEF STAN 91-91
- ASTM specification D1655
- IATA Guidance Material (Kerosene type), NATO Code F-35
Some physical properties for Jet A-1 within ASTM specification D1655:
- Flash point: 38C
- Freezing point: -47C
- Density at 15C: 0.804 kg/L
