Lap Shear Strength

Lap Shear strength is the ability of an adhesive to resist forces that cause the material to adhere to substrates. Shear strength is measured in a tensile test and is measured in pounds per square inch, based on the area of the sheared edge. The shear strength of a structural adhesive is the maximum shear stress in the adhesive before failing under tensile loading. 

Epic uses test method ASTM D1002.
