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 of 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
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, in collaboration
with the European Committee for Standardization (CEN) Technical Committee CEN/TC 139, Paints and
varnishes, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This third edition cancels and replaces the second edition (ISO 4618:2014), which has been technically
revised.
The main changes are as follows:
— the title has been changed from “Terms and definitions” to “Vocabulary”;
— the following terms have been added: brush marks, catalyst, clouding, cold checking, conventional
spraying, crater, creeping, dirt-resistant paint, distinctness of image, DOI, drawdown blade, dry
spray, film applicator, flocculate, nanocomposite coating, nanoparticle, particle, pigment-binder
ratio, primary particle, semi-volatile organic compound, semi-volatile organic compound content,
SVOC, SVOC content, SVOCC;
— the following terms have been deleted: after tack, brush-drag, bubbling, cratering, cutting-in,
dilatant flow behaviour, flash point, flocculation, flow properties, graining, marbling, pseudoplastic
flow behaviour, rheopexy, rheopectic behaviour, rust back, shear-thickening flow behaviour, shear-
thinning behaviour, sheen, tack-free, thixotropic behaviour, thixotropy, UV-curing, viscoelasticity,
viscosity, yield point, yield stress, yield value;
— many definitions have been amended;
— the text has been editorially revised and the bibliography and scope have been updated.

Paints and varnishes — Vocabulary
1 Scope
This document defines terms used in the field of coating materials (paints, varnishes and raw materials
for paints and varnishes).
Terms relating to specific applications and properties are dealt with in standards concerning those
applications and properties, including corrosion protection (see the ISO 12944 series), coating powders
(see ISO 8130-14), electro-deposition coatings (see ISO 22553-1) and rheology (see ISO 3219-1).
Terms on nanotechnologies are harmonized with the ISO 80004 series.
Terms on pigments and extenders are harmonized with ISO 18451-1.
