Adhesives - Wettability - Determination by measurement of contact angle and surface free energy of solid surface

This European Standard specifies a method for the determination of the surface free energy of a solid surface
by measuring the contact angle of a liquid wetting the solid surface. It allows the prediction of the ability of a
particular adhesive to wet a particular adherend. It can be used to characterize surfaces intended for
pre-treatment, coating or bonding.
NOTE 1 In order to determine the surface free energy, the method of measuring the static contact angle is used in
combination with a statistical interpretation.
NOTE 2 The measurement results are influenced by mechanical surface roughness and chemical homogeneity.

Klebstoffe - Benetzbarkeit - Bestimmung durch Messung des Kontaktwinkels und der freien Oberflächenenergie fester Oberflächen

Diese Europäische Norm legt ein Verfahren zur Bestimmung der freien Oberflächenenergie einer festen Ober-fläche durch Messung des Kontaktwinkels einer Flüssigkeit fest, die die feste Oberfläche benetzt. Es gestattet die Voraussage über die Fähigkeit eines bestimmten Klebstoffs ein bestimmtes Fügeteil zu benetzen. Es kann zur Charakterisierung von Oberflächen eingesetzt werden, die zur Vorbehandlung, Beschichtung oder zum Kleben vorgesehen sind.
ANMERKUNG 1   Um die freie Oberflächenenergie zu bestimmen, wird das Verfahren zur Messung des statischen Kontaktwinkels in Kombination mit einer statistischen Auswertung angewendet.
ANMERKUNG 2   Die Messergebnisse werden durch die mechanische Oberflächenrauheit und die chemische Homogenität beeinflusst.

Adhésifs - Mouillabilité - Détermination par mesurage de l'angle de contact et de l'énergie superficielle libre de la surface solide

La présente Norme européenne spécifie une méthode de détermination de l'énergie superficielle libre d’une surface solide par mesurage de l’angle de contact d’un liquide mouillant ladite surface. Elle permet de prévoir l’aptitude d’un adhésif particulier à mouiller un substrat donné. Elle peut être utilisée pour caractériser les surfaces destinées à recevoir un prétraitement, à être revêtues ou collées.
NOTE 1   Pour déterminer l’énergie superficielle libre, la méthode de mesurage de l’angle de contact statique est appliquée en association avec une méthode d’interprétation statistique.
NOTE 2   Les résultats de mesure sont influencés par la rugosité superficielle et l’homogénéité chimique.
