Nota:
1. Durities Brinell: Praecipue ad metiendam duritiem partium fusarum, fabricatarum, metallorum non-ferrorum, lingotum calido-laminatorum et partium recoctarum adhibetur. Ambitus mensurae est ≥HB450.
2. Duritia Rockwelliana: HRA imprimis adhibetur ad exemplaria altae duritiae ad metiendam duritiam superficialem materiarum et superficierum quorum duritia maior est quam HRC67, ut puta carburum cementatum, chalybs nitruratum, etc. Ambitus mensurae est HRA > 70. HRC imprimis adhibetur ad metiendam duritiam partium chalybearum (ut chalybem carbonicum, chalybem instrumentalem, chalybem mixtum, etc.) post refrigerationem vel revenitionem. Ambitus mensurae est HRC20~67.
3. Durities Vickers: ad duritiem partium tenuium et partium laminarum ferrearum metiendam adhibetur, et etiam ad duritiem partium superficialiter induratarum, ut carburizationem, cyanidationem, et nitridationem, metiendam adhiberi potest.
