SCOPE 1.1 This method describes a means for calculating the cetane index of diesel fuels (without cetane improvers) from the aniline point, distillation, density and viscosity. The index, as computed

29、from the prescribed formula, is termed the CGSB Cetane Index (CI). 1.2 A suggested procedure is also outlined in Appendix A to estimate the cetane index, additized (CIA), based on the calculated cetane index for diesel fuels containing diesel ignition improver (DII). This procedure can be used to es

30、timate the combustion quality when CI and DII are used, and a cetane engine test is not performed. The Appendix A does not form a mandatory part of this method. 1.3 The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous.

31、This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior t

32、o its use. 2.

SUMMARY OF METHOD 3.1 The aniline point, the 10%, 50% and 90% distillation points, the density at 15C, and the v

37、iscosity at 40C are determined, and the CGSB Cetane Index (CI) is calculated. 4. SIGNIFICANCE AND USE 4.1 The CGSB Cetane Index is useful for estimating the ASTM cetane number of diesel fuels from properties often routinely determined on the fuels. 4.1.1 This method is more suitable for estimating t

38、he cetane number of Canadian fuels, particularly those of oil sands origin. In the range below 40 cetane number, this method is preferable to that of ASTM D 976 for estimating the ASTM cetane number. Note: The CGSB Cetane Index is not a replacement for the ASTM cetane number as determined by ASTM D

39、613. 4.2 Correlation with Cetane Number Based on a series of 260 Canadian diesel fuels ranging from 28 to 63 cetane number, the expected correlation of the calculated cetane index with the ASTM cetane number will be less than 1.5 cetane numbers for 66% of the fuels evaluated. 5. PROCEDURE 5.1 Anilin

40、e Point Determine the aniline point of the fuel in accordance with ASTM D 611. 5.2 10%, 50% and 90% Distillation Recovery Temperatures Determine the 10%, 50% and 90% distillation temperatures of the fuel corrected for barometric pressure, based on percentage recovery, in accordance with ASTM D 86. 5

41、.3 Density Determine the density of the fuel at 15C in accordance with ASTM D 1298 or D 4052. 5.4 Viscosity Determine the viscosity of the fuel at 40C in accordance with ASTM D 445. 6. CALCULATION 6.1 Calculate the CGSB Cetane Index by means of the following equation: VBBAA 6350.0 5844.0 6150.11 003

PRECISION 8.1 The calculation of the CGSB Cetane Index from the aniline point, distillation points, density and viscosity is exact, and no precision limits can be assigned to the calculation itself. 8

45、.2 The precision of the CGSB Cetane Index is dependent only on the precisions of the original four tests. 8.3 Assuming that test results from the four tests complied with their respective precisions, the following precision statements apply to the calculation of the CGSB Cetane Index. 8.3.1 Repeatab

46、ility The difference between two results obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long term, in the normal and correct operation of the test methods, exceed 0.2 only in one case in twenty. 8.3.2 Reproducibility

47、 The difference between two single and independent results obtained by different operators working in different laboratories on identical test material would, in the long term, in the normal and correct operations of the test methods, exceed 0.5 only in one case in twenty. 9.
