Shear tests

Test types

Lateral load applied normal to face of component

Shear

The most common test is a shear test. Performing a shear test, a bond tester applies lateral load to the sample and shears the bond from it surface.

 

The choice between pull or shear testing depends on the application and the test objectives. We have experience with different test types and can advise you on how to test in order to get the best information for your quality assurance process.
