Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work o f 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 o f
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
di fferent types o f ISO documents should be noted. This document was dra fted 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 o f the elements o f this document may be the subject o f
patent rights. ISO shall not be held responsible for identi fying any or all such patent rights. Details o f
any patent rights identified during the development o f 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 in formation given for the convenience o f users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary in formation

Textiles — Determination o f certain flame retardants —
Part 1:
Brominated flame retardants
WARNING — This International Standard calls for the use o f substances and/or procedures
that may be injurious to health i f adequate precautions are not taken. It re fers only to technical
suitability and does not absolve the user from legal obligations relating to health and sa fety at
any stage. It has been assumed in the dra fting o f this International Standard that the execution
o f its provisions is entrusted to appropriately qualified and experienced people.
1 Scope
This part o f ISO 17881 specifies a test method for determining some brominated flame retardants in
textiles by gas chromatography – mass spectrometry (GC-MS).
The method is applicable to all kinds of textile products.
2 Principle
The flame retardants are extracted from textile specimen by ultrasonic generator with toluene. The flame
retardants in the specimen are identified by GC-MS and quantified by using internal standard method.
3 Reagents
Unless otherwise specified, use only reagents o f recognized analytical grade.
