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/directiveswww.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/patentswww.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

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 non­governmental, 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,

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.

In addition to terms in English and French (two of the three official ISO languages), this document gives

the equivalent terms in German. These terms are published under the responsibility of the member

body for Germany (DIN) and is given for information only. Only the terms and definitions given in the

official languages can be considered as ISO terms and definitions.

L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes

nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est

en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude

a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,

gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.

L’ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui

concerne la normalisation électrotechnique.

Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont

décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents

critères d’approbation requis pour les différents types de documents ISO. Le présent document

Note 2 à l'article: Les cratères peuvent se prolonger dans les couches précédentes du revêtement (3.46) ou

jusqu’au subjectile (3.245).

Note 3 à l'article: Les cratères sont causés par des hétérogénéités localisées dans la tension de surface

du revêtement, le plus souvent dues à des souillures incompatibles à la surface du subjectile, dans le produit

de peinture (3.48) appliqué ou sous forme de corps étrangers particulaires ou de petites gouttes d’huile.

Note 4 à l'article: Un petit cratère dépourvu de bord surélevé est appelé dépression.
