DIN EN ISO 9936:2016-11

This International Standard specifies a method for the determination of the contents of free <(alpha)>-, <(beta)>-, <(gamma)>-, and <(delta)>-tocopherols and tocotrienols in animal and vegetable fats and oils by high-performance liquid chromatography (HPLC). For products containing tocopherol or tocotrienol esters, it is necessary to carry out a preliminary saponification. Milk and milk products (or fat coming from milk and milk products) are excluded from the Scope of this International Standard. The International Standard has been prepared by ISO/TC 34/SC 11 "Animal and vegetable fats and oils" (secretariat: BSI, United Kingdom) of Technical Committee ISO/TC 34 "Food Products", (secretariat: AFNOR, France). The responsible body for the European Standard is CEN/TC 307 "Oil seeds, vegetable and animal fats and oils and their by-products - Methods of sampling and analysis" (secretariat: AFNOR, France). On the national level, the standard is supervised by NA 057-05-05 AA "Gemeinschaftsausschuss für die Analytik von fetten, Ölen, Fettprodukten, verwandten Stoffen und Rohstoffen" (GA Fett) of the German Fat Research Society (DGF) ("Joint committee for the analysis of fats, oils and products thereof, related and primary products") and DIN Standards Committee Food and Agricultural Products (NAL).
