Footwear - Critical substances potentially present in footwear and footwear components - Determination of organotin compounds in footwear materials (ISO 16179:2025)

This document specifies a test method for the qualification and quantification of organotin compounds by applying gas chromatography coupled with mass spectrometry. This test method is applicable to all types of footwear materials except metal hardware (see ISO/TR 16178).

Schuhe - Möglicherweise in Schuhen und Schuhbestandteilen vorhandene kritische Substanzen - Bestimmung zinnorganischer Verbindungen in Schuhwerkstoffen (ISO 16179:2025)

Dieses Dokument legt ein Prüfverfahren zur qualitativen und quantitativen Bestimmung von zinnorganischen Verbindungen durch Anwendung von mit Massenspektrometrie gekoppelter Gaschromatographie fest. Dieses Prüfverfahren gilt für alle Arten von Schuhwerkstoffen, mit Ausnahme von Metall-Beschlägen (siehe ISO/TR 16178).

Chaussures - Substances critiques potentiellement présentes dans les chaussures et les composants de chaussures - Détermination des composés organostanniques dans les matériaux de chaussures (ISO 16179:2025)

L'ISO/TS 16179:2012 spécifie une méthode d'essai permettant de déterminer la présence de composés organostanniques dans les matériaux de chaussures. Cette méthode s'applique à tous les types de matériaux de chaussures.

Foreword
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 with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes
