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

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

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 19403-6:2017), which has been
technically revised.
The main changes are as follows:
— the term 3.2 “advancing angle” has been amended by “advancing contact angle” and the definition
has been reworded;
— the term 3.3 “receding angle” has been amended by “receding contact angle” and the definition has
been reworded;
— the text has been editorially revised and the normative references have been updated.

Introduction
Dynamic contact angles describe the processes on the interface liquid/solid during volume increase
(advancing contact angle) or volume decrease (receding contact angle) of a drop. As an alternative to
the static method (see ISO 19403-2), for the advancing contact angle always a surface area is wetted,
which was previously unwetted. For the receding contact angle, the contact angle during dewetting is
observed. From the difference between advancing contact angle, information on chemical homogeneity
and roughness can be concluded. The receding contact angle is not suitable for the determination of the
surface energy

Part 6:
Measurement of dynamic contact angle
1 Scope
This document specifies a method to measure the dynamic contact angle with an optical method. The
advancing and the receding contact angles are determined.
By means of this defined measurement, the wetting and dewetting properties can be characterized. It
can also be concluded on the morphological and chemical homogeneity of interfaces.

dynamic contact angle
contact angle, which is measured during advancing or receding of the three-phase point
Note 1 to entry: For the definition of “contact angle”, see ISO 19403-1:2017, 3.1.9.
Note 2 to entry: The advancing or receding of the three-phase point can be achieved by changing the volume of
the liquid drop to be measured, by relative movement (immersing and pulling out) of a solid body to an interface,
or by moving the drop over the interface (e.g. rolling off).
