MIL-DTL-16884N
3. REQUIREMENTS
3.1 General. Requirements contained herein are not subject to corrections for tolerance of standard test
methods. If multiple determinations are made by the inspecting laboratory, average results will be used except for
those standard test methods where repeatability data are given. In those cases, the average value derived from the
individual results that agree within the repeatability limits given may be used at the discretion of the inspection
authority, provided an indication is given of the total number of results obtained and the number falling outside of
the repeatability limits. The flash point value is absolute and no value less than 60.0 °C is permissible. For
purposes of determining conformance with these specifications, an observed value or a calculated value shall be
rounded "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance
with the rounding method of ASTM E29.
3.2 Material. The fuel supplied under this specification shall consist of refined hydrocarbon distillate fuel,
containing no residual fuel, and may contain only those additives specified in 3.2.2. The fuel shall be derived from
conventional material sources, synthesized materials, or mixtures thereof. Conventional material sources are defined
as crude oil, natural gas liquid condensates, heavy oil, shale oil, and oil sands. The fuel shall not contain any
intentionally blended oxygenated compounds including fatty acid methyl esters (FAME), as specified in 3.2.3.
3.2.1 Synthesized materials. A maximum of 50 volume percent of the finished fuel (see 6.3.4) may consist of
Synthesized Paraffinic Diesel (SPD) (see 6.3.9) blend components derived from Hydroprocessed Renewable Diesel
(HRD) (see 6.3.6 and 6.3.7) or Fischer-Tropsch (FT) produced SPD. The remainder of the finished fuel must be
comprised of conventional source blending components (see 6.3.3). Fischer-Tropsch Hydroprocessed Synthetic
Paraffinic Diesel (FT-SPD) (see 6.3.5) and HRD derived blend components shall conform to the requirements in
Appendix A. Finished fuel containing synthetic materials shall conform to the properties listed in table I. If the
finished fuel containing synthetic materials requires additives, then only the additives in accordance with 3.2.2
shall be used.
3.2.2 Additives. The additives listed herein may be used either singularly or in combination, provided the
amounts do not exceed those specified herein. When specified (see 6.2), information concerning the type and
dosage rate of each additive used shall be made available when requested by the procuring activity or user. All other
additives are prohibited without prior approval from the cognizant activity below:
Cognizant activity for Fuel Additives:
Commander, Naval Sea Systems Command
Ship Integrity and Performance Engineering (SEA 05P2)
1333 Isaac Hull Avenue, SE, Bldg. 197, Washington Navy Yard, DC 20376
3.2.2.1 Metal deactivator. A metal deactivator, N, N-disalicyclidene-1, 2 propanediamine, may be blended into
the fuel provided the dosage rate does not exceed 5.8 milligrams of active ingredient per liter of fuel (2.2 grams per
100 U.S. gallons or 2 pounds per 1000 barrels).
3.2.2.2 Lubricity improver additives. Lubricity improver additives may be used to meet the lubricity
requirement in table I. The lubricity improver additive shall have an approved formulation in accordance with
MIL-PRF-32490 and shall not exceed the maximum dosage rate prescribed by MIL-PRF-32490.
3.2.3 FAME. The recent mandatory and voluntary introduction of FAME (commonly known as biodiesel) in
the commercial middle distillate marketplace has resulted in the potential for trace amounts of FAME in F-76 fuel.
Fuel supplied under this specification shall not intentionally be blended with FAME. In the event of contamination
with FAME, the fuel supplied under this specification shall not contain more than 0.1 volume percent FAME as
determined by BS EN 14078 or IP 579.
3.3 Physical and chemical requirements. The naval distillate fuel shall conform to the physical and chemical
requirements specified in table I. These tests are performed on the finished product. Where more than one test
method is allowed for a specific requirement, table I identifies the referee test method first, followed by the notation
"(R)".
