Structural adhesives - Corrosion - Part 2: Determination and classification of corrosion to a brass substrate
This 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
Diese Europäische Norm beschreibt ein Verfahren zur Bestimmung der Fähigkeit eines Klebstoffes, ein
Messingmaterial bei angelegter Spannung und hoher Feuchtigkeit zu korrodieren. Die Temperatur, die
Feuchtigkeit, die Zeitspanne der Alterung und die angelegte Spannung sind deshalb so gewählt, um eine
maximale Unterscheidung zwischen der Korrosivität unterschiedlicher Klebstoffe sicherzustellen, und sollen
nicht dazu dienen, unterschiedliche Anwendungsbedingungen nachzustellen.
Adhésifs structuraux - Corrosion - Partie 2: Détermination et classification de la corrosion d’un substrat en laiton
La présente Norme européenne décrit une méthode 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 différencier de
manière optimale la corrosivité de plusieurs adhésifs, et elles ne sont pas destinées à représenter des
conditions particulières d’utilisation.
Konstrukcijska lepila - Korozija - 2. del: Ugotavljanje in razvrstitev korozije na medeninasti preskusni podlagi
Ta evropski standard opisuje metodo ugotavljanja zmožnosti lepila za korozijo na medeninasti preskusni podlagi pod vplivom uporabljene napetosti in visoke vlage. Temperatura, vlaga, čas staranja in uporabljena napetost so izbrani tako, da zagotavljajo maksimalno diferenciacijo med korozivnostjo različnih lepil in niso namenjeni predstavljanju katerega koli posebnega pogoja delovanja.
