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 the following

This document was prepared by Technical Committee ISO/TC 256, Pigments, dyestuffs and extenders.
This second edition cancels and replaces the first edition (ISO 18451-2:2015), of which it constitutes a
minor revision. The changes compared to the previous edition are as follows:
— Clause 2 has been updated;
— the boilerplate of Clause 3 has been updated;
— the typing errors, e.g. missing names of colouring materials, have been corrected;
— the numbering of some footnotes has been corrected.

ISO 18451-2:2018(E)
Introduction
In accordance with ISO 18451-1, it depends on the individual application as to whether a substance is
to be considered as a pigment or as an extender. Substances like aluminium silicate, barium sulfate and
calcium carbonate are taken into consideration in Clauses 4 and 5.
In addition to the examples of the colouring materials, the designation in accordance with the Colour
1)
[1]
Index has been included. However, it is to be noted that for a number of the given designations of
colouring materials (which are partly collective designations) not only one designation in accordance
with the Colour Index is possible, even if in this document only one Colour Index designation is given.
In the “Classification scheme” in Clause 4, some spaces are empty. Corresponding colouring materials
are either without practical importance or they do not exist for physical reasons.
Inorganic dyestuffs, e.g. those for use with enamel, glass, ceramics and food, have been only mentioned
in Clauses 4 and 5 but not classified in accordance with certain aspects. The reason for this is that up to
now, such colouring materials are excluded from the work of ISO/TC 256.
1) The Colour Index (briefly: C.I.) is a work of reference existing since 1925, and comprising all usual colouring
materials and dyestuff chemicals being used as their basis. It is accepted as a standard work in the field of pigment
and dyestuff chemistry.

Classification of colouring materials according to
colouristic and chemical aspects
1 Scope
This document applies to the industry producing colouring materials and the consumer who uses the
products of this industry. In this document, the colouring materials are classified in accordance with
colouristic and chemical aspects.
Some dyestuffs for use in the ceramics and food industries are listed as examples.

4 Classification of inorganic and organic colouring materials in accordance with
colouristic aspects
Inorganic and organic colouring materials are classified in accordance with colouristic aspects as given
in Figure 1.

Figure 1 — Classification of inorganic and organic colouring materials in accordance with
colouristic aspects
The above classification is based on optical effects the reasons of which are given in the following.
White pigments The optical effect is based on light scattering, independent on the wavelength.
Coloured The optical effect is based on light absorption, dependent on the wavelength, com-
pigments bined with light scattering.
Coloured The optical effect is based on light absorption, dependent on the wavelength.

Black The optical effect is based on light absorption, independent on the wavelength, in
colouring the visual range of light.
materials
Effect pigments The optical effect is based at least on one of the following effects:
— in the case of metallic flake pigments on the directed reflectance of mainly flat
shaped and aligned metallic pigment particles;
— in the case of nacreous pigments on the directed reflectance of mainly flat
shaped and aligned transparent small plates;
— in the case of interference pigments on the phenomenon of light interference.
Luminous The optical effect is based on their ability to absorb radiation and to emit it as
colouring light of greater wavelength without delay with regard to time (fluorescence) or
materials with delay with regard to time (phosphorescence).
Examples regarding the classification in accordance with colouristic aspects are given in Table 1.
