For the analysis of “Sustainable Aviation Fuels”, or “SAF” for short, ASTM D7566 is the underlying standard for regenerative kerosene. Unlike classic fuel standards, this specification consists of a main specification for final blends of SAF and fossil kerosene (for use in aircraft turbines), as well as the specifications for the individual SAF blending components themselves.
ASTM D7566 Annex 1:
Fischer-Tropsch (FT-SPK)
ASTM D7566 Annex 2:
Ester / Fatty Acids (HEFA-SPK)
ASTM D7566 Annex 3:
Fermented Sugars (HFS-SIP)
ASTM D7566 Annex 4:
Fischer-Tropsch with Aromatics
(FT-SKA)
ASTM D7566 Annex 5:
Alcohol-to-Jet (AtJ-SPK)
ASTM D7566 Annex 6:
Catalytic Hydrothermolysis (CHJ)
ASTM D7566 Annex 7:
Hydrocarbon-Hydroprocessed Esters and Fatty Acids (HC-HEFA-SPK)
ASTM D7566 Annex 8:
Alcohol-to-Jet with Aromatics
(AtJ-SKA)
SAF
Jet A / Jet A1
Final Blend:
