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.
Peintures et vernis - Mouillabilité - Partie 4: Détermination des fractions polaire et dispersive de la tension superficielle des liquides à partir d’une tension interfaciale (ISO 19403-4:2024)
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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

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 19403-4:2017), which has been technically
revised.
The main changes are as follows:
— in 5.3, the requirement on the wall thickness of the optical cell has been reduced to 2 mm;
— in 5.4, the requirement for the reference liquids has been changed from colourless to transparent;
— the normative references have been updated.
