Oil absorption number (OAN) is a measure of the ability of a carbon black to absorb liquids. This property is afunction of the structure of the carbon black. Either dibutyl phthalate (DBP) or paraffin oil is acceptable for usewith standard pelleted grades, including N-series carbon blacks found in ASTM D 1765, although OAN testingusing paraffin oil on some speciality blacks and powder blacks may result in unacceptable differences ascompared to OAN testing using DBP oil. While studies have shown the two oils to give comparable precision,paraffin oil offers the advantage of being non-hazardous.This International Standard specifies a method using an absorptometer for the determination of the oilabsorption number of carbon black for use in the rubber industry.The same method is used for the determination of the oil absorption number of compressed samples ofcarbon black. The procedure for the preparation of the compressed samples is described in Annex A.
