The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of h.

The deeper a defined indenter penetrates the surface of a specimen with a specified test load, the softer the material that is being tested.
Vickers hardness testing to ASTM E92 is a hardness test method with optical evaluation in which the size of the indentation left on the surface of the test material by a pyramid-shaped diamond indenter (square base and interfacial angle of α = 136°) is measured. The test load is applied precisely and the diagonals of the indentations are used to calculate the Vickers .

ASTM E384: This standard is for hardness testing on a micro-scale, and therefore includes the Vickers and Knoop hardness tests. ISO 6506: This standard mirrors ASTM E10, as it contains the standard method for measuring the Brinell hardness of metals. Note 1: The Vickers and Knoop hardness numbers were originally defined in terms of the test force in kilogram-force (kgf) and the surface area or projected area in millimetres squared (mm 2).Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons (N). However, in practice, the most commonly used force .

load-dependent. In Table 2 are given the Vickers hardness numbers for a test load of 1 kgf. For obtaining hardness numbers when other test loads are used, the Vickers hardness number obtained from Table 2 is multiplied by the test load in kilograms-force (Table 3). N. ote. 1—The Vickers hardness number is followed by the symbol The Vickers Hardness test (ISO 6507) is used to characterize hardness of various solid materials (metals, ceramics, etc.). A diamond pyramid is pressed against the solid with a certain normal load and the hardness is calculated based on the imprint left on the surface. . Standard Hardness Conversion for metals acc. ASTM E 140 – 97 .Microhardness testing per ASTM E-384 gives an allowable range of loads for testing with a diamond indenter; the resulting indentation is measured and converted to a hardness value.
