Structural adhesives - Determination of shear behaviour of structural bonds - Part 2: Thick adherends shear test
 N EN 14869-2

Annotation

This European Standard specifies a test method for determining the shear behaviour of an adhesive in a single lap joint bonded assembly when subjected to a tensile force.

The test is performed on specimens consisting of thick, rigid adherends, with a short length of overlap, in order to obtain the most uniform distribution of shear stresses possible and to minimize other stress states which initiate failure.

This test method may be used to determine:

— the shear-stress against shear-strain curve to failure of the adhesive;

— the shear modulus of the adhesive;

— other adhesive properties that can be derived from the stress/strain curve such as the maximum shear stress and shear strain;

— the effect of temperature, environment, test speed, etc. on these properties.
