MIL-DTL-16884N
TABLE I. Physical and chemical requirements Continued.
NOTES:
1/
If the sample has no visible particulates, but is otherwise not "clear and bright" (see 6.3.2) in accordance with
ASTM D4176, Procedure 1, then the product shall meet the requirements of ASTM D2709, 0.05-volume
percent of water and sediment, maximum. The fuel is acceptable for appearance if the water and sediment
content is 0.05 percent volume or less. If the sample fails ASTM D4176, Procedure 1, because it contains
visible sediment or particulate matter, but meets the requirements of 10 milligrams per liter (mg/L),
maximum, in accordance with ASTM D6217 or ASTM D5452, then the fuel is considered acceptable
provided all other physical and chemical requirements are met.
2/
The demulsification test shall be conducted in accordance with ASTM D1401 with the following exceptions:
(a) Synthetic seawater in accordance with ASTM D1141 shall be the emulsifying fluid.
(b) The test temperature shall be 25 °C.
(c) The demulsification time shall be that required for separation into two layers with no visible cuff at the
interface. A lacy emulsion or cuff which does not form a band shall be disregarded. The
fuel/water/emulsion layer volumes shall be recorded at 1-minute intervals and the demulsification time
reported to the nearest minute.
3/
As the end point of the distillation is approached, if either a thermometer reading of 385 °C or a
decomposition point is observed, the heating shall be discontinued and the procedure resumed as directed in
ASTM D86.
4/
Results from ASTM D2887 shall be reported as "Predicted D86" results by application of the correlation in
the Correlation for Jet and Diesel Fuel appendix of ASTM D2887 to convert the values. ASTM D86 shall
remain as the referee method. Distillation residue and loss limits provide control of the distillation process
during the ASTM D86 test method and do not apply to ASTM D2887.
5/
If either ASTM D5771, ASTM D5772, or ASTM D5773 is used, the temperature recorded in each respective
test shall be rounded to the next lower integer and reported as the ASTM D2500 equivalent cloud point in
accordance with ASTM D5771, ASTM D5772, or ASTM D5773.
6/
The flash point value is absolute and no value less than 60.0 °C is permissible.
7/
If ASTM D5452 is utilized, a minimum 1-liter sample will be used to meet the sample requirement of
ASTM D6217.
8/
If either ASTM D5949, ASTM D5950, or ASTM D5985 is used, the results from these tests shall be based
on the observations at 3 °C temperature intervals and reported as the ASTM D97 equivalent.
9/
The sample size when using ASTM D974 shall be 20.0±2.0 grams.
10/
Requirement applies only to finished fuels containing synthesized materials as defined in Appendix A.
11/
Fuel must meet the requirements for one of the two test methods. If ASTM D189 or ASTM D4530 is
performed in lieu of the referee test method, ASTM D524, the maximum allowable carbon residue shall be
0.14 mass percent.
12/
ASTM D976 is only a valid method when 100 percent of the F-76 is derived from conventional material
sources. ASTM D976 is not an acceptable cetane test method for fuels containing synthesized materials as
defined in Appendix A.
13/
Only nylon membrane filter media (0.8-micrometer pore size) are acceptable as specified in ASTM D5304.
Glass fiber (Type A/E) filter media shall not be used to obtain test results.
14/
Fuel must meet the requirements for one of the two test methods.
15/
If ASTM D2274 is utilized, the test period shall be extended from 16 hours to 40 hours.
16/
Availability of ultra-low sulfur (maximum 0.0015 mass percent) F-76 may be limited in certain regions. A
waiver to deliver higher sulfur fuel may be granted on a case-by-case basis. Final authority to approve sulfur
content waiver is granted by NAVSEA 05P2.
17/
Results by ASTM D3605 shall be reported in mg/L. Original limits in table I still apply.
