Standard Test Method for Determination of Indicated Cetane Number (ICN) of Diesel Fuel Oils using a Constant Volume Combustion Chamber—Reference Fuels Calibration Method

Importancia y uso:

5.1 The ICN value determined by this test method provides a measure of the ignition characteristics of diesel fuel oil used in compression ignition engines.

5.2 This test can be used by engine manufacturers, petroleum refiners, fuel producers and in commerce as a specification aid to relate or match fuels and engines.

5.3 The relationship of diesel fuel ICN determinations to the full scale, variable speed, variable load diesel engine is not completely understood.

5.4 This test can be applied to non-conventional diesel fuels.

5.5 This test determines ICN; it requires a sample of approximately 40 mL and a test time of approximately 25 min.

5.6 This test method is based on the Energy Institute Test Method IP 617.
