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 no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents . ISO shall not be held responsible for identifying any or all such patent rights.

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 216, Footwear, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 309, Footwear, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO/TS 16179:2012), which has been technically revised.

The changes are as follows:

• the technical specification becomes an ISO standard;
• GC-MS/MS technique added in 8.9.3 and in Clause B.2;
• new extraction solvent in Clause 4;
• new Table 1 (certain substances added) in Clause 4;
• change in the safety instructions at the preparation of the sodium tetraethylborate solution in Clause 8;
• sample preparation reference to ISO 21061 in Clause 7;
• new Table 2 (certain substances added) in 8.3.1;
• deletion of the need for duplicate determinations in Clause 7;
• new Annex B for mass spectroscopy;
• deletion of the reference to ISO 22744-1 in the Bibliography.

Introduction

Certain organotin compounds have been identified as carcinogenic. Thus, several countries have restricted them in articles such as footwear, e.g. in the European Union by commission regulation (EU) 276/2010^[1] amending regulation (EC) No 1907/2006^[2].

Further organotin compounds are restricted by footwear brands in their restricted substances lists (RSL).

1 Scope

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).
