The principle of the method specified is placing a weighed test portion in a crucible and subjecting to destructive distillation. The residue undergoes cracking and coking reactions during a fixed period of severe heating. At the end of the specified heat period, the test crucible containing the carbonaceous residue is cooled in a desiccator and weighed. The residue remaining is calculated as a mass percentage of the original test portion. The method may be used to determine amounts of carbon residues in the range of 0,01 % (m/m) to 30,0 % (m/m), left after evaporation and pyrolysis.
