This 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 should lauric oils be analysed by this method.
