Infant formula and adult nutritionals -Determination of total iodine - Inductively coupled plasma mass spectrometry (ICP-MS) (ISO 20647:2015)

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.

Formules infantiles et produits nutritionnels pour adultes - Détermination de la teneur en iode total - Spectrométrie de masse avec plasma à couplage inductif (ICP-SM) (ISO 20647:2015)

ISO 20647:2015 spécifie une méthode de détermination quantitative de la teneur en iode total dans les formules infantiles et produits nutritionnels pour adultes[1]. La méthode s'applique au dosage de l'iode total dans les formules infantiles et dans les produits nutritionnels pour adultes entre 0,5 µg/100 g et 1 500 µg/100 g de produit final reconstitué et dans les produits prêts à servir entre 2,5 µg/100 g et 1 000 µg/100 g par ICP-SM.
La méthode a fait l'objet d'une étude interlaboratoires en utilisant diverses formules infantiles et produits nutritionnels pour adultes. Les niveaux obtenus variaient de 3,47 µg/100 g à 124 µg/100 g. Pour toutes les données de fidélité liées à l'étude interlaboratoires, voir le Tableau A.1.

ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part
in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance wit the
editorial rules of ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

The committee responsible for this document is ISO/TC 34, Food products, Subcommittee SC 5, Milk and
milk products and the International Dairy Federation (IDF), in collaboration with AOAC INTERNATIONAL.
It is being published jointly by ISO and IDF and separately by AOAC INTERNATIONAL. The method
