Overview
This International Standard specifies two methods for the determination, by drying, of the moisture and volatile matter content of animal or vegetable fats and oils: - method A, using a sand bath or hotplate; - method B, using a drying oven. Method A is applicable to all fats and oils. Method B is applicable only to non-drying fats and oils with an acid value less than 4. Under no circumstances are lauric oils be analysed by this method. Milk and milk products (or fat obtained 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).
