MIL-DTL-38219 Turbine Fuel, Low Volatility, Jp-7This specification covers one grade of aviation turbine fuel designated as JP-7. This specification was thoroughly reviewed as a part of acquisition reform. While most of the requirements were converted to performance terms, due to the military-unique nature of the product and the need for compatibility with deployed systems, it was determined that not all requirements could be converted. The issuance of this specification as "detail" is not intended to constrain technology advances in future systems.

3.4 Additives. The additives listed herein shall be used in amounts not to exceed those specified (see 6.4).

Information concerning the type and amount of each additive used shall be made available when requested by the

Procuring Activity or user. Additives other than those listed in the following paragraphs will be permitted only by

special authorization from the acquisition activity.

3.4.1 Antioxidants. To prevent the formation of gums and peroxides, one of the following antioxidants shall be

blended into the fuel immediately after it is processed and before it is exposed to air. The antioxidant shall be added

to the fuel at a concentration of 24 mg of inhibitor (not including weight of the solvent) per liter of fuel (8.4 lb

inhibitor/1000 barrels of fuel):

a. 2,6-ditertiary butyl-4-methylphenol

b. 2,4-dimethyl-6-tertiary butylphenol

c. 2,6-ditertiary butylphenol

d. Mixed tertiary butylphenol composition:

75 percent 2,6-ditertiary butylphenol

10 to 15 percent 2,4,6-tritertiary butylphenol

10 to 15 percent ortho-tertiary butylphenol.

3.4.2 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 redoping the fuel, shall not exceed 5.7 mg/L. Metal

deactivator additive shall not be used in JP-7 unless the supplier has obtained written consent from the Procuring

Activity and user.

3.4.3 Fuel system icing inhibitor. The fuel system icing inhibitor, to be added at a concentration in accordance

with table I, shall conform to MIL-I-85470.

3.4.4 Lubricity additive. A lubricity additive, PWA-536, shall be added in an amount not less than 200 parts per

million (ppm) (weight/weight) and not more than 250 ppm (weight/weight).

3.5 Odor. The odor of the fuel shall not be nauseating or irritating. No substances of known dangerous toxicity

under usual conditions of handling and use shall be present.

3.6 Workmanship. When examined visually, the finished fuel shall be water white; free from undissolved water,

sediment, or suspended matter; and shall be clean and bright at the ambient temperature or at 21�C (70�F),

whichever is higher.
