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 eksimplaren mei hege hurdens om de oerflakhurdens fan materialen en oerflakken mei in hurdens heger as HRC67 te mjitten, lykas sementearre karbid, nitride stiel, ensfh. It mjitberik is HRA> 70. HRC wurdt benammen brûkt om de hurdens fan stielen ûnderdielen (lykas koalstofstiel, arkstiel, legearingstiel, ensfh.) te mjitten nei it blussen of temperjen. 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.
