Structural adhesives - Characterization of a surface by measuring adhesion by means of the three point bending method; English version of DIN EN 1966:2009-07
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.
