Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation. The Vickers hardness test uses a square-based pyramid diamond indenter with an angle of 136º between the opposite faces at the vertex, which is pressed into the surface of the test piece using a prescribed force. Load range is 0,3-0,5-1-3-5-10-30 kg.
