Petroleum products. Determination of carbon residue. Micro method Ingestion-build-232773 mainframe computers were still the1 Scope 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 products under specified conditions. NOTE 1 The carbon residue value serves as an approximation of the tendency of petroleum products to form carbonaceous deposits under similar degradation conditions, and may be useful in the assessment of relative
