ISO 14869-1 Torsional Shear of Structural Adhesives
ISO 14869-1 (ISO 11003-1:2001, modified) specifies a shear test for the characterization of adhesives in a bond. The shear stress/ strain properties of the adhesive (including the shear modulus) are useful for advanced design work. For this test method, use a torsion-testing machine with a capacity of 300 to 1000 N-m.
ISO 14869-2 Thick Adherends Shear
ISO 14869-2 (ISO 11003-2:2001 Modified) 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 secant shear modulus and maximum shear stress; the effect of temperature, environment, test speed, etc., on these properties.
