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.

1 Scope
This document describes a method for determining short-chain chlorinated paraffins (C -C ) (SCCPs)
10 13
in textiles using carbon skeleton reaction gas chromatography with a flame ionization detector (GC-FID).
It is applicable to all kinds of textile products.

4 Principle
SCCPs are extracted from textile specimens by an ultrasonic generator with n-hexane/acetone. SCCPs
are pretested by gas chromatography with an electron capture detector (GC-ECD) and then quantified
by GC-FID using an external standard method. SCCPs are dechlorinated by reacting with hydrogen
to generate straight-chain alkane (C -C ) under the action of a PdCl catalyst. GC-FID is used to
10 13 2
determine the quantity of straight-chain alkane following an external standard method, and then the
quantity of SCCPs is calculated.
5 Reagents
Unless otherwise specified, only reagents of recognized analytical grade are used.
5.1 Short-chain chlorinated paraffins (SCCPs) (C -C , 51,5 % Cl), 100 µg/ml in cyclohexane.

5.2 Short chain chlorinated paraffins (SCCPs) (C -C , 55,5 % Cl), 100 µg/ml in cyclohexane.
