DIN EN 16715:2014-04

This European Standard specifies a test method for the quantitative determination of ignition delay of middle distillate fuels intended for use in compression ignition engines. The method utilizes a constant volume combustion chamber with direct fuel injection into heated, compressed synthetic air. A dynamic pressure wave is produced from the combustion of the product under test. An equation converts the ignition delay and combustion delay determined from the dynamic pressure curve to the derived cetane number (DCN). This method is applicable to diesel fuels, FAME and blends of diesel fuels and FAME.
