FOOTNOTES:
1. The sample size when using ASTM D974 shall be 20.0±2.0 grams.
2. 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 recorded as the ASTM D97 equivalent.
3. The demulsification test shall be conducted in accordance with ASTM D1401 with the following exceptions:
· Synthetic seawater in accordance with ASTM D1141 shall be the emulsifying fluid.
· The test temperature shall be 25 °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 recorded to the nearest minute.
4. 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.
TEST SLATES:
Test Slate 1- Test Slate 1 is for testing of Marine Gas Oil (MGO) samples Test Slate 2-Test Slate 2 is modified MIL-STD-3004-1 B-1 testing for F-76 special diagnostic samples Test Slate 3- Test Slate 3 is MIL-STD-3004-1 B-2 testing for F-76 special diagnostic samples
ADDITIONAL NOTES:
1. Any deviation from the test methods cited above shall be submitted for approval as part of the proposal.
2. All temperatures shall be reported in degrees Celsius (°C).
3. Fuel may be dyed in accordance with government regulations. For dyed fuel, report color of fuel only (red, blue, green, etc.). An ASTM test method is not needed
