MIL-DTL-25524E(USAF)
3.4.2 Metal deactivator. A metal deactivator, N,N'-disalicylidene-1,2-propandiamine or N,N'-disalicylidene-
1,2-cyclohexanediamine, may be blended into the fuel in an amount not to exceed 5.7 mg of active ingredient per
liter of fuel (2 pounds of active ingredient per 1,000 barrels of fuel). Metal deactivator additive shall not be used
in JPTS unless the supplier has obtained written consent from the Procuring Activity and user.
3.4.3 Fuel system icing inhibitor. The use of a fuel system icing inhibitor shall be mandatory. The icing
inhibitor shall be in accordance with MIL-I-85470. The point of injection of the additive and the type of the
additive shall be determined by agreement between the purchase authority and the supplier.
3.4.4 Special additive. The fuel shall contain from 8.6 to 11.4 mg/L of fuel (3 to 4 pounds/1,000 barrels of fuel)
of Octel America JFA-5 additive.
3.4.5 Corrosion inhibitor/lubricity improver additive. A corrosion inhibitor/lubricity improver additive
qualified for JPTS and conforming to MIL-I-25017 shall be blended into the fuel by the supplier. The amount
added shall be equal to or greater than the minimum effective concentration and shall not exceed the maximum
allowable concentration listed in the latest revision of QPL-25017. The supplier or transporting agency, or both,
shall maintain and upon request make available to the Government evidence the corrosion inhibitor/lubricity
improver additive used is equal in every respect to the qualified products listed on QPL-25017.
3.4.5.1 Approved corrosion inhibitor/lubricity improver additives. The following corrosion inhibitor/lubricity
improver additives qualified for JPTS on QPL-25017 are:
a. HITEC 580
b. NALCO/EXXON 5403
c. MOBILAD F800
d. IPC 4410
e. IPC 4445
f. TOLAD 3220
g. PETROLITE NC-351
3.4.6 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.
3.5 Workmanship. At the time of Government acceptance, the finished fuel shall be clear, bright, and visually
free from undissolved water, sediment, or suspended matter. In case of dispute, the fuel shall be clear and bright
at 21C (70F) and meet the table I particulate matter requirement.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follow:
a. First article inspection (see 4.2).
b. Conformance inspection (see 4.3).
4.2 First article inspection. Test requirements of 3.3.1 shall be complied with prior to bid on any product
required under this specification. This test shall be conducted in accordance with 4.5.3.
4.2.1 Sample. One 208-liter (55-gallon) drum of fuel from the first batch that represents the product offered to
the Government under any contract shall be forwarded to AFRL/PRSF, Bldg 490, 1790 Loop Road N, Wright-
Patterson AFB OH 45433-7103. Test data that show the results of tests required by 3.3 and 3.3.1 performed on
products produced or blended in an identical manner to the batch sample shall accompany the 208-liter (55-gallon)
sample forwarded under each contract. The Government will perform tests as necessary to confirm or validate the
contractor's test results. Failure of the storage stability test will render the contractor ineligible for further contract
award, pending assurance by the supplier to the satisfaction of the Air Force Research Laboratory's Fuels Branch
(AFRL/PRSF) that any future product will meet the storage stability requirement. The storage stability test must
then be repeated on the improved product to prove that the product is totally acceptable.
