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.

3.1 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 areas on the
surface. The significance limits can be specified by the user in accordance with standard laboratory methods.
1) This term is defined in DIN 1342-1.
ISO 19403-1:2017(E)
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 areas 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 surfaces and is indicated as
free energy in relation to the surface (unit mJ/m ). The term interfacial tension pertains to the interaction with
liquids and is indicated as force per length unit (mN/m). The respective indices “l” for “liquid” and “s” for “solid”
indicate the phases involved.

interfacial free energy (3.1.3) of a solid surface
3.1.5
surface tension
σ
l
interfacial tension of a liquid surface in equilibrium with its vapour phase
Note 1 to entry: The surface tension is indicated as force per length unit (mN/m). Its numerical value corresponds
to the free energy of the interface or surface.
Note 2 to entry: The surface tension corresponds to the work which shall be done in order to enlarge a given
surface by a specific value.
3.1.6
interfacial energy
σ
sl
energy on the phase interface between a solid and a liquid phase
3.1.7
three-phase point
point at which solid phase, liquid phase and vapour phase are in contact with each other
Note 1 to entry: See Figure 1.
3.1.8
base line
straight line through both three-phase points (3.1.7)
Note 1 to entry: See Figure 1.
3.1.9

θ
angle to the base line (3.1.8) within the drop, formed by means of a tangent on the drop contour through
one of the three-phase points (3.1.7)
