About this file
This is a specifications attachment for fuel testing requirements in a federal contract. The document outlines two distinct test slates that contractors must perform on fuel samples using specified ASTM (American Society for Testing and Materials) and ISO test methods. Test Slate 1 is modified MIL-STD-3004-1 B-1 testing applicable to F-76 special diagnostic samples and includes nine fuel property tests: acid number, appearance, lubricity (HFRR), sulfur content, particulate contamination, storage stability, water and sediment by centrifuge, and trace elements. Test Slate 2 applies to Marine Gas Oil (MGO) samples and is significantly more comprehensive, requiring 18 fuel property tests including acid number, appearance, ash, biodiesel content, carbon residue, cetane index, color, cloud point, density, flash point, lubricity, pour point, sulfur, viscosity, particle count, particulate contamination, water, demulsification, and storage stability.
The specifications include detailed footnotes and exceptions to standard test methods. Notable requirements include using a 20.0±2.0 gram sample size for ASTM D974 acid number testing, recording pour point results at 3°C temperature intervals when using alternative methods, and conducting demulsification tests at 25°C using synthetic seawater per ASTM D1141 with specific criteria for separation endpoint determination. The document allows contractors to submit deviations from cited test methods for approval as part of proposals. All temperatures must be reported in degrees Celsius. For dyed fuel, contractors need only report the fuel color (red, blue, green, etc.) without requiring an ASTM test method. Storage stability testing may use either the preferred ASTM D5304 method or the allowable ASTM D2274 method with an extended 40-hour test time instead of the standard 16-hour duration.

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 modified MIL-STD-3004-1 B-1 testing for F-76 special diagnostic samples Test Slate 2- Test Slate 2 is for testing of Marine Gas Oil (MGO) 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
