This International Standard specifies a method for determining the amount of carbon residue left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities. The method is generally applicable to relatively non-volatile petroleum products which partially decompose on distillation at atmospheric pressure. Petroleum products containing ash-forming constituents as determined by ISO 6245 will have an erroneously high carbon residue, depending upon the amount of ash formed. The carbon residue value of burner fuel serves as a rough approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. Similarly, provided amyl nitrate is absent (or if it is present, provided the test is performed on the base fuel without additive) the carbon residue of diesel fuel correlates approximately with combustion chamber deposits. The carbon residue value of gas oil is useful as a guide in the manufacture of gas from gas oil while the carbon residue value of crude oil residuums, cylinder and bright stocks are useful in the manufacture of lubricants.
