DIN EN ISO 10370:2015-03

This document (EN ISO 10370:2014) has been prepared by Technical Committee ISO/TC 28 "Petroleum products and lubricants" (secretariat: NEN, Netherlands)in collaboration with Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin" (secretariat: NEN, Netherlands). The responsible German body is Working Committee NA 062-06-42 AA "Prüfung von flüssigen Kraftstoffen und Heizölen ("Testing of liquid fuels and fuel oils")" of the Section "Mineralöl- und Brennstoffnormung" ("Standardization of Petroleum, Fuels, Lubricants and Related Products") at DIN Standards Committee Materials Testing (NMP). This document 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. For products which yield a residue in excess of 0,10 % (m/m), the test results are equivalent to those obtained by the Conradson carbon residue test in the range of 0,10 (m/m) to 25,0 (m/m). This document is also applicable to petroleum products which consist essentially of distillate material, and which may yield a carbon residue below 0,10 % (m/m). On such materials, a 10 % (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 and non-volatile additives present in the sample add to the carbon residue value and are included in the total value reported.
