This European Standard specifies a test method for the determination of cetane numbers (“CN”) in diesel fuel oils using a standard single cylinder, four-stroke cycle, indirect injection engine. The cetane number provides a measure of the ignition characteristics of diesel fuel oil in compression ignition engines. The cetane number is determined at constant speed in a compression ignition test engine equipped with a swirl chamber. This European Standard is applicable to distillate fuels and fatty-acid methyl esters (FAME) as well as paraffinic diesel fuels, including those containing FAME, ignition-improvers or other additives, intended for use in diesel engines. The Cetane Number scale comprises a range from zero to 100, but typical testing is currently performed in the range from about 40 to about 75 CN. This engine test procedure may be used for other fuels such as synthetics and vegetable oils. However, samples with fuel properties that interfere with the gravity-based pre-supply pressure to the fuel pump e.g. due to high viscosity can only be used to a limited extent. Precision data for such fuels are not available at this stage. Precision data for paraffinic diesel fuels are currently under development.
