3.1 Materials. The fuels supplied under this specification shall be refined hydrocarbon distillate fuel oils, which contain additives in accordance with 3.3. The feedstock from which the fuel is refined shall be crude oils derived from petroleum, tar sands, oil shale, or mixtures thereof.

3.2 Chemical and physical requirements. The chemical and physical requirements of the finished fuel shall meet the requirements in section 3 and Table I, when tested in accordance with the specified test methods.

3.3 Additives. If specified in the contract or purchase description (see 6.2), information concerning the type and amount of each additive used shall be made available.

3.3.1 Antioxidants. Immediately after processing (i.e., during the rundown into feed/batch tank) and before the fuel is exposed to the atmosphere, an approved antioxidant shall be added to all JP-5 fuel and to JP-4 fuel that contains blending stocks that have been hydrogen treated to prevent the formation of gums and peroxides after manufacture. JP-4 fuel that does not contain hydrogen treated blending stocks may have the antioxidant added. The concentration of antioxidant to be added shall be as follows:

a.	For JP-5 and hydrogen treated JP-4: Not less than 17.2 mg nor more than 24.0 mg of active ingredient per liter of fuel (6.0 to 8.4 lb/1000 barrels).
b.	For JP-4 fuel not hydrogen treated, if added, not more than 24.0 mg of active ingredient per liter of fuel (8.4 lb/1000 barrels).

3.3.1.1 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-dimethyphenol 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. Metal deactivator additive shall not be used in JP-4 or JP-5 unless specified in the contract or purchase description (see 6.2). A metal deactivator may be used if approved by the procuring activity and the user. If JP-5 is to be used by the Navy, written consent for the use of metal deactivator shall also be obtained from NAVAIR 4.4.5. If approved, the metal deactivator, N,N’-disalicylidene-1,2-propanediamine, shall 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 redoping the fuel shall not exceed 5.7 mg/L.

3.3.3 Corrosion inhibitor/lubricity improver. A corrosion inhibitor/lubricity improver in accordance with MIL-PRF-25017 shall be blended into the JP-4 and JP-5. The amount added shall be equal to or greater than the minimum effective concentration and shall not exceed the maximum allowable concentration for an approved source as specified in the latest revision of QPL-25017. The point of injection of the corrosion inhibitor/lubricity improver shall be as specified in the contract or purchase description (see 6.2).

3.3.4 Fuel system icing inhibitor. A fuel system icing inhibitor shall be used. The icing inhibitor shall be in accordance with MIL-DTL-85470. The point of injection of the additive for JP-4 and JP-5 shall be as specified in the contract or purchase description (see 6.2).

3.3.5 Static dissipator additive. A static dissipator additive shall be blended into JP-4 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 shall be as specified in the contract or purchase description (see 6.2) The following static dissipator additive is approved: StadisÒ450, marketed by Octel Starreon LLC, Newark, DE 19702. Static dissipator additive shall not be used in JP-5 unless written consent has been obtained from NAVAIR 4.4.5.

3.3.6 Premixing of additives. Additives shall not be premixed with other additives before injection into the fuel so as to prevent possible reactions among the concentrated forms of different additives.

3.4 Workmanship. At the time of Government acceptance, the finished fuel shall be clear and bright and visually free from undissolved water, sediment, or suspended matter. In case of dispute, the fuel shall be clear and bright at 21°C and shall contain no more than 1.0 mg/L of particulate matter as specified in Table I.
