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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
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
The committee responsible for this document is ISO/TC 256, Pigments, dyestuffs and extenders.
ISO 18451 consists of the following parts, under the general title Pigments, dyestuffs and extenders —

INTERNATIONAL STANDARD ISO 18451-1:2015(E)
Pigments, dyestuffs and extenders — Terminology —
Part 1:
General terms
1 Scope
This part of ISO 18451 defines terms that are used in the field of pigments, dyestuffs and extenders.
For some terms, reference is made to ISO 4618 in which also terms and definitions for colourants are
given, relating to their use in coating materials.
In addition to terms in English and French (two of the three official ISO languages), this part of ISO 18451
gives the equivalent terms in German; these are published under the responsibility of the member
body for Germany (DIN). However, only the terms and definitions given in the official languages can be
considered as ISO terms and definitions.
NOTE Those terms that are defined elsewhere in this part of ISO 18451 are shown in italics.
2 Terms and definitions
