Measuring of hardness or hardness testing

Hardness is a quantity for material that describes how big force that is needed to deform a material. Hardness is not the same as density. Density is a measure of a materials closeness, this means what mass the material has per volume quantity.

Hardness test is an important part of material testing. One distinguishes between two main groups for hardness testing:
•    Plastic measuring, where the testing deforms the sample and causes a remaining mark in the material.
•    Elastic measuring, where the sample regain its original shape after the testing is finished.

Hardness measuring/hardness testing is performed by either measuring the depth of the impact from the indenter or by measuring the size of the impact from the indenter.
One common used definition of hardness in a material is: “the resistance a material exercise against a permanent deformation through penetration of another harder material”.Hardness measuring instruments is often called Durometers, they have their origins in instruments that were used for measuring metal. The world Durometer derives from the Latin word Duro meaning “Hard/Tough”.
