Structural adhesives - Characterization of a surface by measuring adhesion by means of the three point bending method
This European Standard describes a test method to determine ability of a cured adhesive (possibly with a primer) to adhere to a substrate which has had a certain surface finish or with a specific surface preparation by using the "three point bending method".
It is only used for quality assurance and the substrate should be rigid or resistant enough to bending such as steel or aluminium alloys. For other substrates the thickness should be adjusted to the modulus of elasticity or a suitable stiffener should be used.
The adhesive should be polymerisable (curable) without pressure in order to obtain the thickness needed to provide sufficient rigidity, otherwise, a bonded reinforcing piece of the same type and same thickness as the substrate can be substituted for the bloc of adhesive.
It is not suitable for film adhesives.
Strukturklebstoffe - Charakterisierung einer Oberfläche durch Messung der Adhäsion nach dem Dreipunkt-Biegeverfahren
Diese Europäische Norm beschreibt ein Prüfverfahren, bei dem das „Dreipunktbiegeverfahren“ angewendet
wird zur Bestimmung der Fähigkeit eines vernetzten Klebstoffes (gegebenenfalls mit Primer) an einem Fügewerkstoff
zu haften, der eine bestimmte Oberflächenbeschaffenheit hat oder eine spezielle Oberflächenvorbehandlung
erfahren hat.
Dieses Verfahren wird ausschließlich zur Qualitätssicherung angewandt und der Fügewerkstoff sollte starr
oder gegen Biegen ausreichend widerstandsfähig sein, wie z. B. Stahl oder Aluminiumlegierungen. Bei
anderen Fügewerkstoffen sollte die Dicke dem Elastizitätsmodul angepasst oder eine geeignete Versteifung
angewendet werden.
Um eine Dicke zu erreichen, die eine ausreichende Steifigkeit ergibt, sollte der Klebstoff ohne Druckanwendung
polymerisierbar (vernetzbar) sein, andernfalls kann ein verstärkender Block der gleichen Art und
der gleichen Dicke wie der Fügewerkstoff den Klebstoffblock ersetzen.
Das Verfahren gilt nicht für Klebstofffilme.
Adhésifs structuraux - Caractérisation d'une surface par mesure de l'adhérence au moyen de la méthode de la flexion en trois points
La présente Norme européenne décrit une méthode d’essai permettant de déterminer l’aptitude d’un adhésif durci (éventuellement un système adhésif+ primaire) à adhérer à un substrat qui a subi un traitement de surface spécifique ou possède un état de surface particulier, au moyen de la méthode dite «de flexion en trois points».
Cette méthode est utilisée uniquement dans le cadre de l’assurance qualité et il convient que le substrat soit rigide ou suffisamment résistant à la flexion, comme l’acier ou les alliages d’aluminium. Concernant les autres types de substrats, il convient que l’épaisseur soit adaptée selon le module d’élasticité ; il est également possible d’utiliser un raidisseur adapté.
Il convient que l’adhésif soit polymérisable (durcissable) sans pression afin d’obtenir l’épaisseur nécessaire à une rigidité suffisante. Dans le cas contraire, une pièce de renfort collée de même type et de même épaisseur que le substrat peut remplacer le bloc d’adhésif.
Cette méthode ne convient pas aux adhésifs en film.
