A-A-52557 Fuel Oil, Diesel; For Posts, Camps And StationsThis CID covers requirements for two grades of low sulfur diesel fuel oils suitable for use in ground compression-ignition and gas turbine engines and other diesel fuel consuming equipment. The two grades of fuel are not suitable for aircraft engines. This diesel fuel is identified as NATO Code Number F-54. This CID does not cover diesel fuels intended for use in areas where ambient temperatures lowerthan -32 deg. C generally occur.

3.2 Fuel stabilizer additive. When specified (see 7.3), a fuel stabilizer additive/biocide conforming to MIL-S-53021 shall be blended into the fuel to improve the suitability of fuels for long term storage (more than six months) and for use in pre-positioned or standby equipment by preventing fuel deterioration and microbiological growth (see 7.4). Additive concentrations are given in the latest revision of QPL-53021.

3.3 Corrosion inhibitor/lubricity improver. When specified (see 7.3), a corrosion inhibitor/lubricity improver conforming to MIL-PRF-25017 shall be blended into the fuel. Additive concentration limits are given in the latest revision of QPL-25017.

3.4 Fuel system icing inhibitor. When specified (see 7.3), a fuel system icing inhibitor conforming to MIL-DTL-85470 shall be blended into the fuel to purge small quantities of water from the fuel system and to prevent the formation of ice crystals. The additive concentration shall not exceed 0.15 volume percent when tested in accordance with (IAW) FED-STD-791, methods 5327, 5330, 5340, or 5342.

3.5 Performance requirements.

3.5.1 Physical and chemical requirements. The maximum cloud point (see 7.3) shall be equal to or lower than the tenth percentile minimum ambient temperature for the area in which ambient temperatures for U.S. locations are shown in Appendix X4 of ASTM D975 (10th Percentile Minimum Ambient Air Temperatures for the United States (Except Hawaii)).

3.5.2 Particulates. Total particulate level as measured IAW ASTM D6217 shall not exceed 10 milligrams/liter (mg/L).

4. REGULATORY REQUIREMENTS.

4.1 Clean Air Act requirements. Under authority of the Clean Air Act, the U.S. Environmental Protection Agency (EPA) issues limits on the maximum sulfur level, the maximum aromatic content or minimum cetane index on diesel intended for on-road use. Details of the EPA regulations and test methods are given in Part 80 of Title 40 of the Code of Federal Regulations (40 CFR 80). Some states, notably California, have more restrictive aromatic content limits. Specifics may be obtained by contacting the Air Quality Office of the state environmental office or headquarters.

4.2 Dye. The Internal Revenue Service (IRS) requires that a red dye, identified as Solvent Red 164 (alkyl derivatives of azo benzene azo naphthol), must be added to all non-taxable diesel fuel as a means of identification. The minimum concentration is provided in 40 CFR 80.

5. PRODUCT CONFORMANCE. The diesel fuel oil provided shall meet the salient characteristics of this CID, conform to the producer’s own specifications, standards, and quality assurance practices, and be the same product offered for sale in the commercial market. The Government reserves the right to require proof of such conformance.
