Rockwell scale - Wikipedia

The Vickers test can be used for all metals and has one of the widest scales among hardness tests. The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be … See more 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 … See more It was decided that the indenter shape should be capable of producing geometrically similar impressions, irrespective of size; the impression should have well-defined … See more To convert the Vickers hardness number to SI units the hardness number in kilograms-force per square millimeter (kgf/mm ) has to be … See more The fin attachment pins and sleeves in the Convair 580 airliner were specified by the aircraft manufacturer to be hardened to a Vickers Hardness specification of 390HV5, the '5' meaning five kiloponds.
