1 Scope
This International Standard specifies a method for determining the amount of carbon residue, in the range of 0,01 % (m/m) to 30,0 % (m/m), left after
evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming tendency. The method is generally applicable to
relatively non-volatile petroleum products which partially decompose on distillation at atmospheric pressure. Petroleum products containing ashforming
constituents as determined by ISO 6245 will exhibit an erroneously high carbon residue, depending upon the amount of ash formed.
