This International Standard specifies a method for the determination of the amount of carbon residue,in the range 0,10 % (m/m) to 30,0 % (m/m), left after evaporation and pyrolysis of petroleum productsunder specified conditions.NOTE 1 The carbon residue value serves as an approximation of the tendency of petroleum products toform carbonaceous deposits under similar degradation conditions, and may be useful in the assessment ofrelative carbon-forming tendencies of products within the same class. In this case, care should be taken in theinterpretation of results.For products which yield a residue in excess of 0,10 % (m/m), the test results are equivalent to thoseobtained by the Conradson carbon residue test (see ISO 6615[1]) in the range of 0,10 (m/m) to 25,0 (m/m)(for details see Annex A).This International Standard is also applicable to petroleum products which consist essentially ofdistillate material, and which may yield a carbon residue below 0,10 % (m/m). On such materials, a10 % (V/V) distillation residue is prepared by the procedure described in 7.3.1 and 7.3.2 before analysis.Both ash-forming constituents, as defined by ISO 6245[2] and non-volatile additives present in the sampleadd to the carbon residue value and are included in the total value reported.NOTE 2 The presence of organic nitrates incorporated in certain distillate fuels will yield abnormally highvalues for the carbon residue. The presence of alkyl nitrate in the fuel may be detected by ISO 13759.[3]
