EN 1967:2002 (E)4IntroductionThis test has been developed to assess pretreatments for aluminium and is intended for laboratory evaluations.The object was to find /develop a rapid test possessing high sensitivity, which could differentiate between picklingpretreatments, complete CAA/PAA and incomplete CAA/PAA processes. The application of water containing awetting agent changes the mode of failure from the cohesive form, usually found in dry joints, into quasi-adhesivefailure. This latter being associated with a corresponding reduction in the resistance to peeling if the surfaces werenot pretreated according to the complete CAA or PAA process. The failure mechanisms in the boundary layer zoneinitiated by this test are mainly explained by the diffusion of water. The wetting agent essentially improves thesurface wetting.This test is considered to be unsuitable for long term durability prediction. It is expected that if this severe test isapplied to less stable joints it will cause mainly adhesive failure. As a consequence of this the test loses its ability todifferentiate effectively in such circumstances. However, the applicability or other materials and surfacepretreatment methods have not been investigated in detail.SIST EN 1967:2003



EN 1967:2002 (E)51 ScopeThe object of this method is the evaluation of the quality of a surface pretreatment used in the preparation ofaluminium or its alloys.This European Standard specifies a floating roller method for the determination of the peel resistance of highstrength adhesive bonds between one rigid metallic adherend and one flexible metallic adherend when testedunder specified conditions of preparation and testing.NOTEThe use of the floating roller produces more constant numerical data than other peel methods, but it should not beexpected that the flexible metallic adherend will conform to the surface of the roller.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.
