标准摘要
[中文适用范围]： 本国际标准规定了婴儿配方食品和成人营养配方中总碘定量测定的方法。该方法适用于用ICP-MS测量重构最终产品中总碘的含量范围为0.5 µg/100g至1500 µg/100g，以及即食产品的含量范围为2.5 µg/100g至1000 µg/100g。使用各种婴儿配方食品和成人营养产品进行分析时，测得的浓度范围在3.47 µg/100g至124 µg/100g之间。与实验室间研究相关的所有精密度数据见附录A中的表A.1。 [外文原描述]： 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.
