Structural adhesives - Determination of shear behaviour of structural bonds - Part 2: Thick adherends shear test (ISO 11003-2:2001, modified) EN 14869-2:2004

Scope

This part of EN 14869 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:
-shear-stress against shear-strain curve to failure of the adhesive;
-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;
-effect of temperature, environment, test speed, etc., on these properties.
