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. 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. www.iso.org/patents

ISO 16373 consists of the following parts, under the general title Textiles — Dyestuffs:

— Part 2: General method for the determination of extractable dyestuffs including allergenic and
carcinogenic dyestuffs (method using pyridine-water)

ISO 16373-3:2014(E)
Introduction
Due to concerns of consumers over safety and hygiene, many countries have introduced regulations
regarding carcinogenic dyestuffs in textile articles. To support international and national regulations
the development of a test method is very important and this part of ISO 16373 does just that.
The ISO 16373 series deal with dyestuffs used in textile for qualification and quantification.
1)
— ISO 16373-1 includes the definition of the dyestuff, and classes the description of some procedures
to identify qualitatively the dyestuff class used in textile material. The other parts of ISO 16373 are
related to the quantification of some dyestuffs.
— In ISO 16373-2, the principle of the test method is based on extraction using pyridine-water solution,
which has been found to be the most efficient solution to extract a large range of dyestuffs, including
allergenic and carcinogenic dyestuffs.
— In this part of ISO 16373, the principle of the test method is based on extraction using triethylamine-
methanol solution. This solution has been found to be efficient at extracting some dyestuffs in some
cases.
Additional information related to the recovery rate (to characterize the extraction efficiency) obtained
from the application of ISO 16373-2 and this part of ISO 16373 is summarized in ISO 16373-1:—, Annex B.
It is important to note that there are other test methods related to azo dyes, for which a reduction of the
extracted azo dyes leads to the release of some aromatic amines to be detected and determined using
[6][7]
chromatography.
