NCWM's Premium Diesel Fuel Standards & Tests
The following are the five performance properties that comprise the National Conference on Weights and Measures (NCWM) Premium Diesel Fuel Standards.
A Fuel marketer must meet at least TWO standards in order to be able to advertise "Premium Diesel" in states that adopt the NCWM standards.
Energy (Btu) Content: The fuel must have at least 138,700 Btu, as measured by ASTM D-240
Cetane Number: The fuel must have a cetane number of at least 47, as measured by ASTM D-613.
Fuel Injector Cleanliness: The fuel must either pass a CRC rating test with a 10. 0 or less, or it must have a flow loss of 6. 0% or less on the Cummins L-10 test.
Low Temperature Operability: The fuel must provide cold-flow performance down to ASTM D-975 tenth percentile minimum ambient air temperature charts and maps for the region and time of year where the fuel will be sold. This performance must be proven through use of the Low-Temperature Flow Test, also known as ASTM D-4539, on the Cloud Point Test.
Thermal Stability: The fuel must get at least an 80% reflectance measurement using a filter in the Octel F21-61 test.
