Paints and varnishes - Wettability - Part 4: Determination of the polar and dispersive fractions of the surface tension of liquids from an interfacial tension (ISO 19403-4:2024)
This document specifies a test method to determine the polar and dispersive fractions of the surface tension of liquids from an interfacial tension with optical methods. The method can be applied for the characterization of liquid coating materials, especially if drying effects occur during alternative measurement. If applied to liquids with non-Newtonian flow behaviour (see ISO 3219-1:2021, 3.22), restrictions can apply.
Beschichtungsstoffe - Benetzbarkeit - Teil 4: Bestimmung des polaren und dispersen Anteils der Oberflächenspannung von Flüssigkeiten aus einer Grenzflächenspannung (ISO 19403-4:2024)
Dieses Dokument legt ein Prüfverfahren mit optischen Methoden zum Bestimmen der polaren und dispersen Anteile der Oberflächenspannung von Flüssigkeiten aus einer Grenzflächenspannung fest. Das Verfahren kann zur Charakterisierung von flüssigen Beschichtungsstoffen eingesetzt werden, insbesondere, wenn in einer alternativen Messung Trocknungseffekte auftreten. Wenn das Verfahren für Flüssigkeiten mit nicht-newtonschem Fließverhalten (siehe ISO 3219 1:2021, 3.22) angewendet wird, können Einschränkungen auftreten.

Le présent document spécifie une méthode d’essai permettant de déterminer les fractions polaire et dispersive de la tension superficielle des liquides à partir d’une tension interfaciale à l’aide de méthodes optiques. Cette méthode peut être utilisée pour la caractérisation des produits de peinture liquides, en particulier si des effets de séchage se produisent durant le mesurage alternatif. Si elle est appliquée avec des produits liquides de comportement d’écoulement non newtonien (voir l’ISO 3219-1:2021, 3.22), des restrictions peuvent s’appliquer.

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.

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

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 19403-4:2017), which has been
technically revised.
The main changes are as follows:
— in 5.2 the the wall thickness of the optical cell has been restricted to less than 2 mm;
— in 5.3 the requirement for the reference liquids has been changed from colourless to transparent;
— in 5.3, the requirement on the wall thickness of the optical cell has been reduced to 2 mm;
— the text has been editorially revised and the normative references have been updated.

1 Scope
This document specifies a test method to determine the polar and dispersive fraction of the surface
tension of liquids with optical methods. The method can be applied for the characterization of liquid
coating materials, especially when drying effects occur during measurement. The applicability can be
