Antioxidants are still mandatory for synthetic fuels and shall be added prior to or during release from the designated manufacturing site of the ASTM D7566 component.
The types and concentrations of all additives used shall be shown on the original Certificates of Quality and on all other quality documents when they are added downstream of the point of manufacture. When additives are diluted (with hydrocarbon solvent only) to improve handling properties prior to addition, it is the concentration of active ingredient that shall be reported. See Annex A of DEF STAN 91-091 for detailed advice.
Fuel System Icing Inhibitor is not permitted unless agreed by all the participants in a joint system (see also Note 24)
See Note 25 about requirements for management of change in refineries.
Lubricity Improver Additive (LIA) additive may be added to the fuel without prior consent of the joint system participants (see also Note 20)
* When the original dosage of additives is unknown, it has to be assumed that first doping was applied at maximum dose rate.
