Abstract: Mounting apparatus for use with a hardness tester which includes a reciprocating penetrator for measuring hardness properties of the materials to be tested. The mounting apparatus may comprise: an elongated base member having parallel upper and lower flat surfaces and provided with a hole substantially midway between the ends thereof; substantially parallel elongated shoe members attached to the base member adjacent its lower surface for contact with the material to be tested; and components for removably attaching the hardness tester to the base member so that its penetrator is disposed in the base member hole for reciprocal movement therein.

Abstract: Apparatus for testing hardness properties of materials may comprise: a clamping assembly including a housing in which is carried a magnet for magnetically attaching the apparatus to the material being tested and a head assembly having a penetrator member mounted for engagement with said material being tested and for limited axial movement from a first position to a second position; an actuator connected to the penetrator member for applying predetermined loads thereto; and an indicator responsive to axial movement of the penetrator member to measure the hardness of the material.
