Noat:
1. Brinell Hardness: It wurdt fral brûkt om de hurdens fan castings te mjitten, fergoedingen, net-ferriedde metalen dielen, hot-rolde billets en uraled dielen. It mjitferkeap is ≥hb450.
2. Rockwell hurdens: HRA's is fral brûkt foar swierrichheden foar hege hurdens om it oerflak fan materialen te mjitten mei hurdens heger dan HRC67, lykas crcrided stiel, ensfh. It mjitberen is HRA> 70. HRC wurdt fral brûkt om de hurdens fan stielen dielen te mjitten (lykas koalstofstiel, arkstiel, alloy stiel, ensfh.) Nei it efterlizzende as temperjen. It mjitkelder is HRC20 ~ 67.
3. Vickers hurdens: brûkt om de hurdens fan tinne dielen en stielen plaates te mjitten, en kinne ek brûkt wurde om de hurdens fan ûnrêstige dielen te mjitten lykas caribearizing, cananiding, cananiding en nitriding.
