This Standard describes a procedure for evaluating the suitability of an individual instrument for measuring protein in liquid milk.NOTE: This Standard is intended for instruments with multi-component capability such as those that can also determine fat and lactose. However the Standard does not validate the instrument's capabilities for measuring analytes other than protein.
