hardness tester — ▪ device device that indicates the hardness of a material, usually by measuring the effect on its surface of a localized penetration by a standardized rounded or pointed indenter of diamond, carbide, or hard steel. Brinell hardness is … Universalium
Rockwell hardness — (RH ) a measure of the hardness of a metal introduced by Rockwell in 1922. In a Rockwell hardness test, a penetrator makes an indentation in the metal under two constant loads, a minor load (generally 10 kilograms) and then a major load. The… … Dictionary of units of measurement
Barcol hardness test — The Barcol hardness test characterizes the indentation hardness of materials through the depth of penetration of an indentor, loaded on a material sample and compared to the penetration in a reference material. The method is most often used for… … Wikipedia
Knoop hardness — (HK or KHN) a measure of the hardness of a metal introduced by Knoop in 1939. The Knoop test is similar to the Vickers test in that a diamond penetrator is used to indent the sample being tested, but it uses a rhombohedral diamond rather than… … Dictionary of units of measurement
