Noat:
1. Brinell hurdens: It wurdt benammen brûkt foar it mjitten fan de hurdens fan castings, forgings, non-ferro metalen dielen, hot-rolled billets en annealed dielen. It mjitberik is ≥HB450.
2. Rockwell hurdens: HRA wurdt benammen brûkt foar hege-hurdens eksimplaren te mjitten de oerflak hurdens fan materialen en oerflakken mei hurdens heger as HRC67, lykas cemented carbid, nitride stiel, ensfh It mjitting berik is HRA> 70. HRC wurdt benammen brûkt om de hurdens fan stielen dielen te mjitten (lykas koalstofstiel, arkstiel, alloy stiel, ensfh.) Nei quenching of tempering. It mjitberik is HRC20 ~ 67.
3. Vickers hurdens: brûkt om te mjitten de hurdens fan tinne dielen en stielen plaat dielen, en kin ek brûkt wurde om te mjitten de hurdens fan oerflak ferhurde dielen lykas carburizing, cyaniding, en nitriding.
