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, Subcommittee
SC 9, General test methods for 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 second edition cancels and replaces the first edition (ISO 19403-1:2017), which has been technically
revised.
The main changes are as follows:
— in the title, "Terminology" has been changed to "Vocabulary";
— text from the Scope has been moved to the Introduction;
— 3.1.5, 3.1.7, 3.1.8 and 3.1.9 have been slightly modified;
— the following terms and definitions have been added: hydrophobic, superhydrophobic, hydrophilic,
superhydrophilic and superhydrophobic coating;
— Clause 4 has been moved to Annex A;
— Figure 1 and Figure A.1 have been updated;
— the designation of the X-axis in Figure A.2 has been corrected;
— the derivation of Formula (A.4) has been improved;
— Formula (A.6) has been corrected;
— bibliographic entries [1] and [12] have been added and cross-references updated.

Introduction
The ISO 19403 series specifies optical test methods:
— for the measurement of the contact angle;
— for the determination of the surface free energy of a solid surface, including the polar and dispersive
fractions;
— for the determination of the surface tension of liquids, including the polar and dispersive fractions;
— for the checking of the measurement arrangement with reference materials.
The ISO 19403 series can be applied for the characterization of substrates, coatings and coating
materials.
[4]
The applicability can be restricted for liquids with non-Newtonian flow behaviour (see DIN 1342-1 ).

Paints and varnishes — Wettability —
Part 1:
Vocabulary and general principles
1 Scope
This document specifies general terms and definitions for wettability. Some general principles are
described in Annex A. This document is intended to be used in conjunction with ISO 4618.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1 Terms relating to determination of the surface free energy
3.1.1
chemical homogeneity
chemically homogeneous composition of a surface to be examined
Note 1 to entry: The definition regards a purely qualitative assessment of the surface. Regarding the
measurement of the contact angle, a surface is considered chemically and topologically sufficiently homogeneous
if no significant differences of the contact angles can be determined when measuring on several locations on the
surface. The significance limits can be specified by the user in accordance with standard laboratory methods.
3.1.2
topological homogeneity
uniformity of the macroscopic surface, including evenness and smoothness
Note 1 to entry: The definition regards a purely qualitative assessment of the surface. Regarding the
measurement of the contact angle, a surface is considered chemically and topologically sufficiently homogeneous
if no significant differences of the contact angles can be determined when measuring on several locations on the
surface. The significance limits can be specified by the user in accordance with standard laboratory methods.
3.1.3
interfacial free energy
interfacial tension
σ
energy or tension resulting from intermolecular forces on interfaces
Note 1 to entry: The term interfacial energy pertains to the interaction with solid sur
