This International Standard specifies a method for the quantitative determination of total iodine in infant formula and adult nutritional formula.[1] The method is applicable to the measurement of total iodine in infant formula and adult nutritional formula from 0,5µg/100g to 1500µg/100g reconstituted final product and for ready-to-feed products from 2,5µg/100g to 1000µg/100g using ICP-MS. Using various infant formula and adult nutritional products, the method was subjected to an interlaboratory study. Levels obtained ranged from 3,47µg/100g to 124µg/100g. For all precision data related to the interlaboratory study, see TableA.1 located in AnnexA.
