Fiiro gaar ah:
1. Qallafsanaanta Brinell: Inta badan waxaa loo isticmaalaa in lagu cabbiro adkaanta wax shubidda, foornada, qaybaha birta ah ee aan birta ahayn, biraha duuban ee kulul iyo qaybaha la shiiday. Qiyaasta cabbirku waa ≥HB450.
2. Rockwell hardness: HRA waxaa inta badan loo isticmaalaa shaybaarada adag ee adag si loo cabbiro adkaanta dusha sare ee alaabta iyo sagxadaha ee engegnaanta ka sarraysa HRC67, sida carbide sibidhka, birta nitrided, iwm. Cabbirka cabbirku waa HRA>70. HRC waxaa inta badan loo isticmaalaa in lagu cabbiro adkaanta qaybaha birta (sida birta kaarboon, birta qalabka, birta daawaha, iwm.) ka dib marka la damiyo ama la dabcay. Qiyaasta cabbirka waa HRC20 ~ 67.
3. Vickers-engegnaanta: waxaa loo isticmaalaa in lagu cabbiro adkaanta qaybaha khafiifka ah iyo qaybaha saxanka birta, sidoo kale waxaa loo isticmaali karaa in lagu cabbiro qallafsanaanta qaybaha dusha sare sida carburizing, cyanding, iyo nitriding.
