    Vickers hardness test (HV) Knoop hardness test (HK) In microindentation testing, the hardness number is based on measurements made of the indent formed in the surface of the test specimen. The hardness number is based on the applied force divided by the surface area of the indent itself, giving hardness units in kgf/mm 2. Microindentation ...

    The Equotip (later on also called simultaneously as Leeb method) rebound hardness test method was developed in the year 1975 by Leeb and Brandestini at Proceq SA to provide a portable hardness test for metals. It was developed as an alternative to the unwieldy and sometimes intricate traditional hardness measuring equipment.
