Structural adhesives - Corrosion - Part 1: Determination and classification of corrosion to a copper substrate; German version EN 1965-1:2011
Strukturklebstoffe - Korrosion - Teil 1: Bestimmung und Klassifikation der Korrosion eines Kupfermaterials; Deutsche Fassung EN 1965-1:2011
Overview
This European Standard describes a method to determine the ability of a liquid adhesive to corrode a copper substrate under heat ageing conditions. Temperatures and ageing periods are chosen to ensure the maximum differentiation between the corrosivity of different adhesives and are not intended to represent any particular service condition. An abraded and polished copper substrate is coated with a thin film of the liquid adhesive and then aged for 24 h in dry heat at 50 °C or 100 °C. Following this the surface is examined and the extent of tarnishing and/or corrosion is assessed on the basis of discolouration. The test standard is directed at the manufacturers and users of structural adhesives and test laboratories. The Committee responsible for this standard is NA 062-04-55 AA "Prüfung von Konstruktionsklebstoffen, -klebverbindungen und Kernverbunden" ("Testing of structural adhesives, structural adhesive bondings and sandwiches") at DIN.
