Structural adhesives - Qualitative assessment of durability of bonded assemblies - Wedge rupture test (ISO 10354:1992 modified)

This document simulates in a qualitative manner mechanical forces and important environmental influences on an adhesive-bonded joint at a metal polymer interfaces it can also be used as a method of checking the surface preparation of substrates, with a limited detection level.
The test is applicable at the present time to the bonding of aluminium and titanium alloys using thermosetting structural adhesives and primers.
NOTE   This method can also be used for assessing surface preparation of other metals. Considerable caution in the evaluation of comparative results should be exercised in the event that the materials (adhesive plus adherend) and the specimen geometry are varied. Like should be compared with like (only similar adherends bonded with similar adhesives can be compared between themselves).

Strukturklebstoffe - Qualitative Bestimmung der Beständigkeit geklebter Baugruppen - Keilberstprüfung (ISO 10354:1992 modifiziert)

Dieses Dokument legt ein Verfahren fest, das auf qualitative Art und Weise mechanische Kräfte und wichtige
Umwelteinflüsse auf Klebverbindungen an einer Metall/Polymer-Grenzfläche simuliert. Es kann auch als
Verfahren mit beschränkter Nachweisgrenze zur Überprüfung der Oberflächenvorbehandlung von Substraten
verwendet werden.
Die Prüfung ist gegenwärtig auf das Fügen von Aluminium- und Titanlegierungen mit wärmehärtenden
Strukturklebstoffen und Haftvermittlern anwendbar.
ANMERKUNG Dieses Verfahren kann auch zur Bestimmung der Oberflächenvorbehandlung anderer Metalle
verwendet werden. Falls die Werkstoffe (Klebstoff und Fügeteil) und die Probengeometrie variiert werden, sollte höchste
Vorsicht bei der Auswertung von Vergleichsergebnissen gewahrt werden. Gleiches sollte mit Gleichem verglichen werden
(nur ähnliche Fügeteile, geklebt mit ähnlichen Klebstoffen können miteinander verglichen werden).

Adhésifs structuraux - Évaluation qualitative de la durabilité des assemblages collés - Essai de clivage au coin (ISO 10354:1992 modifiée)

La présente Norme européenne simule de manière qualitative les forces mécaniques et les influences
environnementales importantes sur un assemblage collé à l�interface métal-polymère. Elle est également un
moyen de contrôle de la préparation de surface des substrats, avec un niveau de détection limitée.
L�essai s�applique à l�heure actuelle au collage d�alliages d�aluminium et de titane, utilisant des adhésifs
structuraux thermodurcissables et des primaires.
NOTE La méthode peut également être utilisée pour caractériser la préparation de surface d�autres métaux. Pour
cela, il convient de prendre beaucoup de précautions dans l�évaluation des résultats comparatifs dans le cas où les
matériaux (adhésif + support) et la géométrie de l�éprouvette varient. Il convient de comparer ce qui est comparable (seuls
des supports identiques collés avec des adhésifs identiques peuvent être comparés entre eux).
