1.1 This automated laboratory test method covers the quantitative determination of the ignition characteristics of conventional diesel fuel oil, oil-sands based fuels, blends of fuel containing biodiesel material, diesel fuel oils containing cetane number improver additives, and is applicable to products typical of ASTM Specification D 975 grades No. 1-D and 2-D regular and low-sulfur diesel fuel oils, European standard EN 590, and Canadian standards CAN/CGSB-3.517 and 3.6-2000. The test method may also be applied to the quantitative determination of the ignition characteristics of diesel fuel blending components.
1.2 This test method measures the ignition delay and utilizes a constant volume combustion chamber with direct fuel injection into heated, compressed air. An equation correlates an ignition delay determination to cetane number by Test Method D 613, resulting in a derived cetane number (DCN).
1.3 This test method covers the ignition delay range from 3.3 to 6.4 ms (61 to 34 DCN). The combustion analyzer can measure shorter and longer ignition delays, but precision may be affected. There is no information about how DCNs outside the 34 to 61 range compare to Test Method D 613 cetane numbers.
