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).
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
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 38, Textiles, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile
products, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).

4 Principle
The organotin compounds are extracted from the material of a textile product with a methanol-
ethanol mixture using tropolone as a complexing agent. The mono- and di-organotin-tropolone
complexes and tri-organotin cations formed in the extraction procedure are directly analysed by a
liquid chromatograph with a tandem mass spectrometer (LC-MS/MS). This method does not require
additional derivatization step.
Table 1 indicates the list of organotin compounds which can be analysed with this document.
This document is also applicable for further organotin compounds provided that the method is validated
