ISO 7208|IDF 22:2008 specifies the reference method for the determination of the fat content of liquid skimmed milk, whey and buttermilk. It is a particularly accurate gravimetric method especially for the purpose of establishing the operating efficiency of cream separators.ISO 7208|IDF 22:2008 also specifies the reference method for establishing correction tables for procedures with skimmed milk butyrometers.
