ISO 12228-2:2014 PDF

Scope: This part of ISO 12228 specifies a procedure for the gas chromatographic determination of the contents and composition of sterols and triterpene dialcohols in olive and olive pomace oils. For the determination of the contents and composition of sterols in all other animal and vegetable fats and oils, ISO 12228-1 is to be used. This part of ISO 12228 is technically identical to IOC Standard COI/T.20/Doc. No. 30 (November 2011).
