Revision of D2414-21 Standard Test Method for Carbon Black—Oil Absorption Number (OAN)


For EFA oil used in OAN/cOAN testing, aromatic impurities could be present from the original raw materials or could be a contamination from manufacturing process. These impurities can significantly affect OAN/cOAN test results; therefore, the amount of aromatic impurities needs to be minimized. A new UV-Vis test was developed for use as a new oil specification. The procedure can also be used for optional oil qualification in QC laboratories.
