This Standard sets out a method, using an iodide-selective electrode, for the determination of the iodide content of raw liquid milk and pasteurized milk. The method is applicable to raw liquid milk which is fresh, or freshly thawed if the sample was frozen, and which contains no added preservative.

This Standard sets out a method, using an iodide-selective electrode, for the determination of the iodide content of raw liquid milk and pasteurized milk.NOTE: The result may not include protein-bound iodine.
