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 voluntary nature of standards, the meaning of ISO specific terms and
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
URL: www .iso .org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 256, Pigments, dyestuffs and extenders.
This second edition cancels and replaces the first edition (ISO 18451-1:2015), which has been technically
revised. The main changes compared to the previous edition are as follows:
— the definition for colour difference (3.21) has been aligned with ISO 18314-4;
— the definition for extender (3.34) has been aligned with ISO 3262-1;
— the definitions for full shade (3.41) and mass tone (3.69) have been interchanged to align them with
the practical use and with definitions in other standards, e.g. ISO 787-25;
— a note has been added to definitions 3.34 (extender) and 3.81 (nanoextender) concerning the use of
the term “filler” as synonym for “extender” in some industries, e.g. rubber and paints;
— the terms nanomaterial (3.82), engineered nanomaterial (3.82.1), manufactured nanomaterial
(3.82.2) and incidental nanomaterial (3.82.3) have been added;
— “may” has been changed to “can” in several notes;
— the text has been editorially revised.
A list of all parts in the ISO 18451 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at https: //www .iso .org/members .html.
In addition to text written in the official ISO languages (English, French or Russian), this document
gives text in German. This text is published under the responsibility of the member body for Germany
(DIN) and is given for information only. Only the text given in the official languages can be considered
as ISO text.
