Paints and varnishes - Wettability - Part 7: Measurement of the dynamic contact angles and the roll-off angle on a tilt stage (ISO 19403-7:2024)
This document specifies a method for the dynamic measurement of the roll-off angle on a tilt stage of a liquid drop on a solid surface. This document also specifies how the dynamic advancing and receding contact angles of the drop rolling off can be determined. The roll-off angle determined through this method can be applied when evaluating easy-to-clean or anti-adherent surfaces.
Beschichtungsstoffe - Benetzbarkeit - Teil 7: Messung der dynamischen Kontaktwinkel und des Abrollwinkels auf einem Neigetisch (ISO 19403-7:2024)
Dieses Dokument legt ein Verfahren zur dynamischen Messung des Abrollwinkels auf einem Neigetisch eines Flüssigkeitstropfens auf einer festen Oberfläche fest. Dieses Dokument legt ebenfalls fest, wie der dynamisch fortschreitende und rückschreitende Kontaktwinkel des abrollenden Tropfens bestimmt werden kann. Der nach diesem Verfahren bestimmte Abrollwinkel kann bei der Beurteilung von „easy-to-clean“-Oberflächen oder Antihaftoberflächen angewendet werden.
Peintures et vernis - Mouillabilité - Partie 7: Mesurage des angles de contact dynamiques et de l’angle de roulement sur un plan incliné (ISO 19403-7:2024)
Le présent document spécifie une méthode de mesure dynamique de l’angle de roulement sur un plan incliné d’une goutte de liquide sur une surface solide. Le présent document spécifie également une méthode permettant de déterminer les angles de contact d’avancée et de recul dynamiques de la goutte qui roule. L’angle de roulement déterminé par cette méthode peut être appliqué lors de l’évaluation de surfaces anti‑adhérentes ou à nettoyage facile.

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.

This second edition cancels and replaces the first edition (ISO 19403-7:2017), which has been technically
revised.
The main changes are as follows:
— the title of the document has been changed;
— the term 3.2 “advancing angle” has been replaced by “dynamic advancing contact angle” and the definition
has been reworded;
— the term 3.3 “receding angle” has been replaced by “dynamic receding contact angle” and the definition
has been reworded;
— the minimum size of the text samples has been changed to 4 cm × 4 cm;
— the use of ethylene glycol as test liquid has been deleted;
— the normative references have been updated.
