1 Principle
A sample, in a refractory thimble, is extracted with hot toluene until the residue reaches constant mass. The mass of residue, calculated as a percentage, is reported as “sediment by extraction”.
This standard is equivalent to the international standard "Crude Petroleum and Fuel Oils -Determination of Sediment-Extraction Method" (ISO 3735-1975).
