Rubber compounding ingredients. Carbon black. Determination of oil absorption number (OAN) and oil absorption number of compressed sample (COAN) Ingestion-build-51215 The method under BS 4401-71 Scope Oil absorption number (OAN) is a measure of the ability of a carbon black to absorb liquids. This property is a function of the structure of the carbon black. Either dibutyl phthalate (DBP) or paraffin oil is acceptable for use with standard pelleted grades, including N series carbon blacks found in ASTM D1765, although OAN testing using paraffin oil on some speciality blacks and powder blacks might result in unacceptable differences as
