. An equation converts an ignition delay determination to a derived cetane number (DCN).
1.3 This test method covers the ignition delay range from a minimum value of 35.0 DCN (ignition delay of 4.89 ms) to a maximum value of 59.6 DCN (ignition delay of 2.87 ms). The average DCN result for each sample in the ILS ranged from 37.29 (average ignition delay of 4.5894 ms) to 56.517 (average ignition delay of 3.0281 ms).
1.4 The values stated in SI units are to be regarded as standard. No other units o
