Adhesives — Determination of strength of bonded joints using a bending-shear method
This International Standard describes a procedure for the determination of the strength of adhesive joints, using a bending-shear method. The method can only be used for comparing adhesives, and the results cannot be used for design purposes.
Adhesives — Determination of the time to rupture of bonded joints under static load
This International Standard describes a procedure for the determination of the time to failure of a bonded joint, using a specimen which is statically loaded under specified conditions. This method can only be used for comparing adhesives, and the results cannot be used for design purposes
