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.

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 information
ISO 16373-1 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 248, Textiles and textile products, in collaboration with ISO Technical Committee TC 38, Textiles,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 16373 consists of the following parts, under the general title Textiles — Dyestuffs:
— Part 1: General principles of testing coloured textiles for dyestuff identification
— Part 2: General method for the determination of extractable dyestuffs including allergenic and
carcinogenic dyestuffs (method using pyridine-water)
— Part 3: Method for determination of certain carcinogenic dyestuffs (method using triethylamine/methanol)

ISO 16373-1:2015(E)
Introduction
The ISO 16373- series deals with dyes used in textiles for qualification and quantification.
This part of ISO 16373 includes the definition of the classes of dyes, the description of some procedures
to identify qualitatively the class of dyes used in textile material.
The other parts of ISO 16373 are related to the quantification of some dyes.
— The principle of the test method in ISO 16373-2 is based on the extraction using pyridine-water
solution, which has been found to be the most efficient solution to extract a large range of dyes,
including allergenic and carcinogenic dyes.
— The principle of the test method in ISO 16373-3 is based on the extraction using triethylamine-
methanol solution. This solution has been found efficient to extract some dyes in some cases.
Additional information related to the recovery rates (to characterize the extraction efficiency) obtained
from the application of ISO 16373-2 and ISO 16373-3 are summarized in 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
chromatography (See Bibliography/Aromatic amines determination).

WARNING — This document calls for the use of substances/procedures that may be injurious
to the health/environment if appropriate conditions are not observed. It refers only to
technical suitability and does not absolve the user from legal obligations relating to health and
safety/environment at any stage.
1 Scope
This part of ISO 16373 gives the definition of the colourant classes and the relationship to textile fibres.
It describes some procedures to identify qualitatively the colourant class used in textile material.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
colourant
dye or pigment
3.2
dye
dyestuff
water-insoluble or water-soluble molecule which has dyeing affinity with fibre
Note 1 to entry: The defining difference between a dye and a pigment is its solubility in an aqueous medium. In
this part of ISO 16373, the term “affinity” is used as a qualitative expression, although affinity is the quantitative
expression of substantivity and usually expressed in Joules per mole, where substantivity is the attraction
between a substrate and a dye or other substance under precise conditions where the latter is selectively
extracted from the application medium by the substrate.
ISO 16373-1:2015(E)
3.3
pigment
water-insoluble molecule which has no dyeing affinity with fibre
Note 1 to entry: The defining difference between a dye and a pigment is its solubility in an aqueous medium. In
this part of ISO 16373, the term “affinity” is used as a qualitative expression, although affinity is the quantitative
