About this file

This attachment to a South Carolina diesel fuel tank cleaning contract specifies fuel quality standards based on ASTM D975, the standard specification for diesel fuel oils. The document outlines minimum testing and treatment requirements that all fuel must meet, establishing performance parameters across multiple quality metrics. The fuel must maintain a flash point minimum of 125°F for safe handling, appear clear and bright at 75°F, and contain no more than 0.05% water and sediment by volume. Additional specifications include a maximum carbon residue of 0.20%, API gravity between 30.0 and 39.0, distillation recovery between 540°F minimum and 640°F maximum at 90% recovery, viscosity range of 1.90 to 4.10, and sulfur content not exceeding 1.0%. The fuel must achieve a maximum corrosion rating of #3, maintain residue at end point below 3.0%, and contain no more than 10 Mg/L of particulate contamination.

Additional quality requirements mandate a minimum cetane index of 40 to ensure proper ignition capability, accelerated storage stability not exceeding 3.0 Mg/L per ASTM D5304 testing, and zero microbial contamination as verified through ASTM D6469 testing. These standards apply to both #1 and #2 diesel fuel grades and are intended to ensure fuel quality for safe storage, proper engine performance, and compliance with legislative requirements governing emissions and engine wear. All fuel deliveries must be tested and treated to meet these minimum standards of the latest ASTM D975 edition prior to use or storage.

ATTACHMENT D

Fuel MUST be tested and treated to the minimum standards of the latest edition of ASTM D975 – Standard Specification for Diesel Fuel Oils.

ASTM D975 — Diesel Fuel Specifications (Following excerpts from ASTM D975 provided for reference only :)

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 (D1796, D1744 and D2709).

0.05 maximum, % volume

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: (D6469) 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
