The Vickers hardness measurement principle is similar to Brinell hardness. A diamond quadrangular pyramid indenter with an opposite angle of 136 ° was used to press the surface of the material with a specified test force F. The test force is removed after holding for a specified time, and the hardness value is expressed by the average pressure on the unit surface area of the regular

Shore hardness is often used as an indication of flexibility or stiffness, which is called flexural modulus. Flex Modulus measures resistance to bending, whereas hardness measures resistance to indentation. However, within a TPE family there exists a direct relationship between these properties; as hardness increases, so does flexural modulus

The Mohs hardness test is one of the earliest attempts at defining and comparing the hardness of mineral materials. The Mohs scale consists of values from 1 to 10, which correlate with the ability of the test material to withstand scratching by progressively harder minerals. It is typically used for geological purposes.

Hardness is important from an engineering standpoint because resistance to wear by either friction or erosion by steam, oil, and water generally increases with hardness. There are three main types of hardness measurements: Scratch hardness. Scratch hardness is the measure of how resistant a sample is to permanent plastic deformation due to

Shore Hardness and IRHD Scales Compared. Elastomeric materials are usually measured with either a Shore A Scale Durometer or an IRHD dead load system. These tests are designed for use with samples approximately 6mm thick, and a surface area sufficient to permit at least 3 test points 5mm apart and 13mm from the edge of the material.
