Diesel fuel cetane number testing.
Cetane testing labs determine diesel fuel cetane numbers and other regulatory protocols. The cetane number, cetane index, and derived cetane number (IQT) tests measure the ignition quality of diesel, gasoil, biodiesel, heating gasoil and number-two fuel oil fuels.
Cetane tests measure diesel and fuel oil characteristics related to fuel quality. Intertek cetane labs measure fuels at refineries, storage facilities and pipelines for cetane ratings and other properties.
