About this file
This is a technical specification document for diesel fuel testing and maintenance standards issued by the Greater Orlando Aviation Authority for switchgear and generator systems. The document outlines ASTM D975 diesel fuel specifications that must be met for fuel used in emergency generator and fuel delivery systems at Orlando International Airport (MCO) and Orlando Executive Airport (ORL) in Florida.
The specification establishes minimum testing and treatment requirements across fourteen critical parameters. Key requirements include a minimum flash point of 125°F for safe handling, clear and bright appearance at 75°F, water and sediment content not exceeding 0.05 percent, carbon residue limited to 0.20 percent maximum, API gravity between 30.0 and 39.0, distillation characteristics with a minimum of 540°F and maximum of 640°F at 90 percent recovery, viscosity range of 1.90 to 4.10, sulfur content capped at 1.0 percent, corrosion rating not exceeding #3, residue at end point limited to 3.0 percent, particulate contamination not to exceed 10 Mg/L, cetane index minimum of 40, accelerated storage stability maximum of 3.0 Mg/L, and zero tolerance for microbial contamination. These specifications apply to both #1 and #2 diesel fuel grades and are essential to ensure proper operation, longevity, and safety of emergency generator and fuel delivery systems at both airport facilities.

ASTM D975 – DIESEL FUEL SPECIFICATIONS
Fuel Must Be Tested and Treated To These Minimum Specifications
Test Parameters : Implications and Uses Specifications
Flash Point: (D93) in degrees F. The minimum temperature at which fuel vapors will ignite under a low flame. Important for safe handling and storage.
125°F = Minimum for #2 Diesel Fuel
Appearance: @ 75° F is a visual examination of the fuel. Dark and/or cloudy fuel suggests a need for remediation.
“Clear and Bright”
Water and Sediment: shows the level of contamination by water and sediments. 0.05 maximum Carbon Residue: (D524) a measure of the carbon depositing tendencies of a fuel when heated in a bulb under prescribed conditions.
0.20 maximum
API Gravity: @ 60°F is the density of the fuel. Deviation from the normal range will alter the classification of the fuel for its intended use.
Range: 30.0 – 39.0
Distillation: (D86) process by which the fuel is distilled and recovered at specified levels. Defines its evaporation characteristics; is important for complete combustion.
540°F = minimum 640°F = maximum @ 90% recovered
Viscosity: (D445) the measure of resistance to flow of a liquid; important for consistency, injector flow, and good atomization.
Range: 1.90 – 4.10
Sulfur: (D5453) a measure of sulfur content. Important to minimize engine wear and to meet legislation.
1.0 maximum
Corrosion: (D130) rates the tendency for fuel to attack metal surfaces in the distribution and storage network, and in the engine fuel system.
#3 = maximum
Residue at End Point: in per cent suggests contamination of the fuel by higher boiling compounds.
3.0% = maximum
Particulate Contamination: in Mg/L is the level of solid particulate matter recovered from the fuel which can lead to blockage of the fuel flow, starvation of and damage to the fuel pump, and damage to the diesel engine.
10 Mg/L = maximum
Cetane Index: (D976) shows the ability of the fuel to ignite properly. Specified as a limitation on the amount of high aromatic components.
40 = minimum
Accelerated Storage Stability: (D5304) a procedure for assessing the potential long-term storage stability. Using oxygen over pressure at a specified temperature for a set period of time to simulate the degradation of the fuel on standing.
3.0 Mg/L= maximum
For grades :
#1 Diesel fuel #2 Diesel fuel
Microbial Contamination: (D6490) the level of a variety of algae growth in the fuel which blocks the flow of fuel by filter blanking and degrades the quality of the fuel.
None Allowed
