The measuring process of the Rockwell test is carried out in three steps. The ease with which the hardness test can be made has made it the most common method of inspection for metals and al-loys. The hard-ness commonly mentioned in the various data sheets refers to the standard measuring method by DIN or ASTM. In contrast, the depth of indentation caused by the indenter is measured in the depth measurement methods (only Rockwell is standardised). The formula for calculating the Vickers hardness value is as follows: Vickers Hardness = (Depth of Indentation / 3.2) x Kg/mm. Why so valuable? PI Range of application. The Vickers hardness number is also determined by the load over the surface area of the indentation as like Brinell number. 8. In Vicker's Hardness testing we use the same testing principle as the Brinell Test. ers testers were developed for test loads of to 0kgf that produce rather large indents. The length of both diagonals formed on the test surface is measured, and the average is used for calculating the hardness, given by the ratio F/A (where F is the force or load, in kgf; and A is the surface area of the indentation, in sq. Use the test procedure to measure the concentration of the sample. The indentation depth serves as a measure of the hardness!
