ISO 20647:2015规定了婴儿配方奶粉和成人营养配方奶粉中总碘的定量测定方法。[1] 该方法适用于使用ICP-MS测定0.5μg/100g至1500μg/100g婴儿配方奶粉和成人营养配方奶粉中的总碘，以及2.5μg/100g至1000μg/100g即食食品中的总碘。 使用各种婴儿配方奶粉和成人营养产品，对该方法进行了实验室间研究。获得的浓度范围为3,47μg/100 g至124μg/100 g。 有关实验室间研究的所有精度数据，见附录A中的表A.1。

ISO 20647:2015 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 0,5 μg/100g to 1 500 μg/100g reconstituted final product and for ready-to-feed products from 2,5 μg/100 g to 1 000 μg/100 g using ICP-MS. Using various infant formula and adult nutritional products, the method was subjected to an interlaboratory study. Levels obtained ranged from 3,47 μg/100 g to 124 μg/100 g. For all precision data related to the interlaboratory study, see Table A.1 located in Annex A.
