Structural adhesives - Corrosion - Part 2: Determination and classification of corrosion to a brass substrate
This part of the present European standard describes a method to determine the ability of an adhesive to corrode a brass substrate under the influence of an applied voltage and high humidity. The temperature, humidity, ageing period and applied voltage are chosen to ensure the maximum differentiation between the corrosivity of different adhesives and are not intended to represent any particular service condition.
Strukturklebstoffe - Korrosion - Teil 2: Bestimmung und Klassifikation der Korrosion eines Messingmaterials
Anwendungsbereich
Dieser Teil der vorliegenden Europäischen Norm beschreibt ein Verfahren zur Bestimmung der Fähig-keit
eines Klebstoffes, ein Messingmaterial bei angelegter Spannung und hoher Feuchtigkeit zu korro-dieren.
Die Temperatur, die Zeitspanne der Feuchtigkeitsalterung und die angelegte Spannung sind so
gewählt, dass sichergestellt wird, dass es möglich ist, bei der Prüfung zwischen der Korrosivität unter-schiedlicher
Klebstoffe maximal zu unterscheiden. Es ist nicht beabsichtigt, unterschiedliche Anwen-dungsbedingungen
nachzustellen.
Adhésifs structuraux - Corrosion - Partie 2: Détermination et classification de la corrosion d'un substrat en laiton
La présente partie de cette Norme européenne décrit une méthode d'essai permettant de déterminer l'aptitude d'un adhésif à corroder un substrat en laiton sous une certaine tension et dans des conditions de forte humidité. La température, l'humidité, la durée du vieillissement et la tension appliquée sont choisies de façon à optimiser la possibilité qu'offre cet essai à faire la distinction entre la corrosivité de différents adhésifs, et elles ne sont pas envisagées pour modéliser des conditions particulières de service.

1 Scope
This part of the present European standard describes a method to determine the ability of an adhesive to corrode a
brass substrate under the influence of an applied voltage and high humidity. The temperature, humidity, ageing
period and applied voltage are chosen to ensure the maximum differentiation between the corrosivity of different
adhesives and are not intended to represent any particular service condition.
