This specification includes the requirements for Ultra Low Sulfur Diesel (ULSD). ULSD fuel will have ≤ 15 ppm (0.0015%) sulfur. Refer to
ASTM D5453, ASTM D2622, or ISO 20846, ISO 20884 test methods.
(2)
A fuel with a higher cetane number is recommended in order to operate at a higher altitude or in cold weather.
(3)
“Via standards tables, the equivalent API gravity for the minimum density of 801 kg / m
3
(kilograms per cubic meter) is 45 and for the maximum
density of 876 kg / m
3
is 30”.
(4)
The values of the fuel viscosity are the values as the fuel is delivered to the fuel injection pumps. Fuel should also meet the minimum viscosity
requirement and the fuel should meet the maximum viscosity requirements at 40 °C (104 °F) of either the ASTM D445 test method or the ISO
3104 test method. If a fuel with a low viscosity is used, cooling of the fuel may be required to maintain “1.4 cSt”or greater viscosity at the fuel in-
jection pump. Fuels with a high viscosity might require fuel heaters in order to lower the viscosity to “1.4 cSt” at the fuel injection pump.
(5)
Follow the test conditions and procedures for gasoline (motor).
(6)
The lubricity of a fuel is a concern with ultra low sulfur fuel. To determine the lubricity of the fuel, use the ISO 12156-1 or ASTM D6079 High
Frequency Reciprocating Rig (HFRR) test. If the lubricity of a fuel does not meet the minimum requirements, consult your fuel supplier. Do not
treat the fuel without consulting the fuel supplier. Some additives are not compatible. These additives can cause problems in the fuel system.
