MIL-DTL-25524 Turbine Fuel, Aviation, Thermally StableThis 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 \(see 6.1\) 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. This specification covers one grade of turbine fuel designated as JPTS \(see 6.1\).

4.3 Conformance inspection. Test for the acceptance of individual lots shall consist of tests for all requirements

specified in section 3, except storage stability. Quality conformance inspection shall include the test requirement

herein. Contractor shall send a 7.08 liter (2 gallon) sample of each batch of fuel produced under any contract to a

designated acquisition activity laboratory for acceptance testing.

4.3.1 Inspection lot. For acceptance purposes, individual lots shall be examined as specified herein and subjected

to tests for all requirements cited in section 3.

4.3.2 Sampling plans

4.3.2.1 Sampling for verification of product quality. Each bulk or packaged lot (see 6.5) of material shall be

sampled for verification of product quality in accordance with ASTM D4057 or ASTM D4177, or both, except

where individual test procedures contain specific sampling instructions.

4.3.2.1.1 Sample containers. A number of jet fuel properties are very sensitive to trace contamination that can

originate from sample containers. Refer to ASTM D4306 for recommended sample containers.

4.3.2.2 Sampling for examination of filled containers for delivery. A random sample of filled containers shall

be selected from each lot. The samples shall be examined in accordance with 4.5.1.3.

4.3.2.3 Special samples. One 208-liter (55-gallon) drum of fuel from the first production lot that represents the

product offered to the Government under an initial contract will be forwarded to the Air Force Research

Laboratory at AFRL/PRSF, Bldg. 490, 1790 Loop Rd N, WPAFB OH 45433-7103. Test data that shows the

results of tests required by 3.3 shall accompany the 208-liter (55-gallon) sample. The Government will perform

tests as necessary to confirm or validate the company's test results. A complete report of analysis shall be

forwarded to the same address for all lots of fuel product under any Government contract. Failure of any tests

conducted within 12 months after receipt of the fuel sample shall render the contractor ineligible for further

contract award, pending verification of the quality of the product to the satisfaction of the acquisition activity.

4.3.3 Inspection. Inspection shall be performed in accordance with method 9601 of FED-STD-791.

4.3.4 Batch sample. AFRL/PRSF reserves the right to have a 18.9-liter (5-gallon) sample of each batch of fuel

produced under any contract forwarded to AFRL/PRSF, Bldg 490, 1790 Loop Road N, Wright-Patterson AFB OH

45433-7103. This sample will be stored at Wright-Patterson AFB and will represent a retained sample from each

batch of fuel produced. All specification tests may be performed any time within 12 months from date of

manufacture. Failure of any test will render the contractor ineligible for further contract award, pending

verification of the quality of the product to the satisfaction of Air Force Research Laboratory's Fuels Branch

(AFRL/PRSF). The contracting officer and contractor will be promptly advised of any failures.

4.4 Inspection conditions. Requirements contained in table I are absolute, as defined in ASTM E29, and shall not

be subject to correction for test tolerances. If multiple determinations are made, results falling within any specified

repeatability and reproducibility tolerances may be averaged. For rounding off of significant figures, ASTM E29,

absolute method, shall apply to all tests required by this specification.

4.5 Methods of inspection

4.5.1 Examination of product

4.5.1.1 Visual inspection. Samples selected in accordance with 4.3.1 shall be visually examined for compliance

with 3.5.

4.5.1.2 Examination of empty containers. Before filled, each empty unit container shall be visually inspected for

cleanliness and suitability in accordance with ASTM D4057.

4.5.1.3 Examination of filled containers. Samples taken as specified in 4.3.2 shall be examined for conformance

to MIL-STD-290 with regard to fill, closure, sealing, leakage, packaging, packing, and markings. Any container

with one or more defects under the required fill shall be rejected.
