MIL-DTL-83133H
3.3 Additives. The type and amount of each additive used shall be made available when
requested by procuring activity or user (see 6.2.d). The only additives approved for use are those
referenced in this specification.
3.3.1 Antioxidants. Immediately after processing and before the fuel is exposed to the
atmosphere (such as during rundown into feed/batch tankage), add an approved antioxidant formulation
(3.3.1.1) or combination of approved antioxidant formulations in order to prevent the formation of gums
and peroxides after manufacture. The concentration of antioxidant to be added shall be:
a. Not less than 17.2 milligrams (mg) nor more than 24.0 mg of active ingredient per liter (L) of
fuel (6.0 to 8.4 lb/1000 barrels) to all JP-8 fuel that contains blending stocks that have been hydrogen
treated or SPK derived from hydrotreated, hydrocracked, or hydroisomerized products of a Fischer-
Tropsch or HEFA process.
b. At the option of the supplier, not more than 24.0 mg of active ingredient per liter of fuel
(8.4 lb/1000 barrels) may be added to JP-8 fuels that do not contain hydrogen treated blending stocks or
SPK derived from hydrotreated, hydrocracked, or hydroisomerized products of a Fischer-Tropsch or
HEFA process.
3.3.1.1 Antioxidant formulations. The following antioxidant formulations are approved:
a.
2,6-di-tert-butyl-4-methylphenol
b.
6-tert-butyl-2,4-dimethylphenol
c.
2,6-di-tert-butylphenol
d.
75 percent min-2,6-di-tert-butylphenol
25 percent max tert-butylphenols and tri-tert-butylphenols
e.
72 percent min 6-tert-butyl-2,4-dimethylphenol
28 percent max tert-butyl-methylphenols and tert-butyl-dimethylphenols
f.
55 percent min 2,4-dimethyl-6-tert-butylphenol and
15 percent min 2,6-di-tert-butyl-4-methylphenol and
30 percent max mixed methyl and dimethyl tert-butylphenols
3.3.2 Metal deactivator. A metal deactivator, N,N'-disalycylidene-1,2-propanediamine, may be
blended into the fuel. The concentration of active material used on initial batching of the fuel at the
refinery shall not exceed 2.0 mg/L. Cumulative addition of metal deactivator when re-doping the fuel shall
not exceed 5.7 mg/L. Metal deactivator additive shall not be used in JP-8 unless the supplier has
obtained written consent from the procuring activity and user.
3.3.3 Static dissipater additive. An additive shall be blended into the fuel in sufficient
concentration to increase the conductivity of the fuel to within the range specified in Table I at the point of
injection. The point of injection of the additive shall be determined by agreement between the purchasing
authority and the supplier. The following electrical conductivity additive is approved: Stadis® 450
marketed by Innospec Fuel Specialties LLC (formerly Octel Starreon LLC), Newark, DE 19702.
3.3.4 Corrosion inhibitor/lubricity improver additive. A corrosion inhibitor/lubricity improver (CI/LI)
additive in accordance with MIL-PRF-25017 shall be blended into the F-34 (JP-8) grade fuel by the
contractor. The CI/LI additive is optional for F-35. The amount added shall be equal to or greater than
the minimum effective concentration and shall not exceed the maximum allowable concentration listed in
QPL-25017. The contractor or transporting agency, or both, shall maintain and upon request shall make
available to the Government evidence that the CI/LI additives used are equal in every respect to the
qualification products listed in QPL-25017. The point of injection of the CI/LI additive shall be determined
by agreement between the purchasing authority and the supplier.
