Organization: ASTM
Publication Date: 1 January 1993
Status: inactive
Page Count: 5
ICS Code (Petroleum products in general): 75.080
scope:

1. Scope

1.1 This test method covers the determination of the amount of carbon residue (Note 1) formed after evaporation and pyrolysis of petroleum materials under certain conditions and is intended to provide some indication of the relative coke forming tendency of such materials.

1.2 The test results are equivalent to the Conradson Carbon Residue test (Test Method D 189).

1.3 This test method is applicable to petroleum products that partially decompose on distillation at atmospheric pressure and was tested for carbon residue values of 0.10 to 30 % (m/m). Samples expected to be below 0.10 weight % residue should be distilled to remove 90 % of the flask charge (see Section 9 in Test Method D 189 for details). The 10 % bottoms remaining is then tested for carbon residue by this test method.

1.4 Ash-forming constituents as defined by Test Method D 482, or non-volatile additives present in the sample will add to the carbon residue value and be included as part of the total carbon residue value reported.

1.5 Also in diesel fuel the presence of alkyl nitrates, such as amyl nitrate, hexyl nitrate or octyl nitrate, causes a higher carbon residue value than observed in untreated fuel, which may lead to erroneous conclusions as to the coke-forming propensity of the fuel. The presence of alkyl nitrate in the fuel may be detected by Test Method D 4046.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety practices and to determine the applicability of regulatory limitations prior to use. For specific hazard statements see Note 5, Note 6, Note 7, and Note 8.
