A soundness test that requires saw cuts to be made on two or three surfaces of a test specimen. Once the specimen has been cut, it is broken by using one of three methods: pulling it in a tensile tester, supporting either end while hitting the center with a hammer, or hitting one end with a hammer while the other end is held in a vise. Once fractured, the fracture surface is then examined for slag inclusions, cracks, porosity, incomplete joint penetration, and incomplete fusion.
