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).

ISO 19403-6:2017(E)
Introduction
Dynamic contact angles describe the processes on the interface liquid/solid during volume increase
(advancing angle) or volume decrease (receding angle) of a drop in horizontal position. As an
alternative to the static method (see ISO 19403-2), for the advancing angle always a surface area is
wetted, which was previously unwetted. For the receding angle, the contact angle during dewetting is
observed. The difference between advancing angle and receding angle is a sign of different chemical or
physical homogeneity (morphology, topology) or roughness. The receding 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 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.
