Umhloli wokuqina wokuqina we-Universal empeleni iyithuluzi lokuhlola elibanzi elisekelwe kumazinga e-ISO kanye ne-ASTM, okuvumela abasebenzisi ukuthi benze ukuhlola kokuqina kwe-Rockwell, i-Vickers kanye ne-Brinell ethuluzini elifanayo.Umhloli wokuqina wokuqina uhlolwa ngokusekelwe ezimisweni ze-Rockwell, Brinell, ne-Vickers esikhundleni sokusebenzisa ubudlelwano bokuguqulwa kwesistimu yokuqina ukuze kutholwe amanani obunzima obuningi.
Isikali sokuqina se-HB Brinell sifanele ukukala ubulukhuni bensimbi ekhonjiwe, ama-alloy angeyona insimbi, nezinsimbi ezihlukahlukene ezifakwe emanzini nezipholile.Ayilungele ukulinganisa amasampula noma izinto zokusebenza eziqine kakhulu, ezincane kakhulu, ezizacile kakhulu, futhi ezingavumeli ukuhlehlisa okukhulu phezulu.
Isikali sobulukhuni be-HR Rockwell sifanele: isikhunta sokuhlola, ukukalwa kokuqina kwezingxenye eziphathwa ukushisa okucishiwe, ezicishiwe nezipholile.
Isikali sokuqina se-HV Vickers sifanele: ukulinganisa ubulukhuni bamasampuli nezingxenye ezinezindawo ezincane kanye namanani aphezulu okuqina, ukuqina kwezendlalelo ezifakiwe noma ama-coatings ngemva kokwelashwa okuhlukahlukene kwendawo, kanye nokuqina kwezinto ezincane.
Okulandelayo isingeniso sochungechunge olusha lwabahloli bokuqina be-Universal: kanye nesikrini sokuthinta i-Universal Hardness Tester
Ihlukile kumhloli wokuqina wokuqina we-Universal, isihloli sokuqina sokuqina kwesizukulwane esisha se-Universal sisebenzisa ubuchwepheshe benzwa yamandla kanye nesistimu yempendulo ye-close-loop force ukuze kuthathelwe indawo imodeli yokulayisha isisindo, okwenza ukulinganisa kube lula nevelu elilinganiselwe lizinze kakhudlwana.
