Nòt:
1. Brinell dite: Li se sitou itilize pou mezire dite nan Distribisyon, Forgings, pati metal ki pa FERROUS, billets cho-woule ak pati rkwit. Ranje mezi a se ≥HB450.
2. Rockwell dite: HRA se sitou itilize pou espesimèn ki wo dite pou mezire dite sifas materyèl ak sifas ki gen dite ki pi wo pase HRC67, tankou carbure simante, asye nitrure, elatriye. Ranje mezi a se HRA> 70. HRC se sitou itilize pou mezire dite pati asye (tankou asye kabòn, asye zouti, asye alyaj, elatriye) apre trempe oswa tanperaman. Ranje mezi a se HRC20 ~ 67.
3. Vickers dite: yo itilize pou mezire dite nan pati mens ak pati plak asye, epi yo ka itilize tou pou mezire dite nan pati sifas ki fè tèt di toujou tankou carburizing, cyaniding, ak nitriding.
