Kubathengi abaninzi abaneemfuno eziphezulu zokuchaneka kwabavavanyi bobunzima, ukulinganiswa kwabavavanyi bobunzima kubeka iimfuno ezingqongqo ngakumbi kwiibhloko zobunzima. Namhlanje, ndiyavuya ukwazisa uthotho lweebhloko zobunzima beKlasi A.—Iibhloko zobunzima beRockwell, iibhloko zobunzima beVickers, iibhloko zoBulukhuni beBrinell, i-HRA, i-HRB, i-HRC, i-HRE HRR, i-HV, i-HBW njl.njl.
Iibhloko zobunzima beKlasi A zixhomekeke kwiimfuno ezingqongqo kakhulu ngokweendlela zokucubungula, unyango lomphezulu, kunye neenkqubo zonyango lobushushu. Inkqubo yokuvelisa ezi bhloko zobunzima ibandakanya iindlela zokulungisa eziphucukileyo. Amaziko okulungisa e-CNC asetyenziswa ngokusemgangathweni ukuqinisekisa ukuba ubukhulu beebhloko zobunzima buhlangabezana nemigangatho echanekileyo kakhulu. Ipharamitha nganye yokusika ilungiswa ngononophelo ukunciphisa naziphi na iimpazamo ezinobukhulu.
Kwicala lonyango lomphezulu, kusetyenziswa iindlela ezikhethekileyo zokugqiba umphezulu. Ukupholisha ngekhemikhali kunye nokulapha ngokuchanekileyo kwenziwa ukuze kwenziwe umphezulu onoburhabaxa obuphantsi kakhulu. Oku akunciphisi nje kuphela ukuphazamiseka kokungalungi komphezulu ngexesha lenkqubo yokulinganisa ubulukhuni kodwa kwandisa ukunamathelana phakathi kwe-indenter yomvavanyi wobulukhuni kunye nomphezulu webhloko yobulukhuni, ukuqinisekisa iziphumo zokulinganisa ezichanekileyo.
Inkqubo yokunyanga ubushushu yeebhloko zobunzima beKlasi A nayo ilawulwa ngononophelo. Iifurniture zonyango lobushushu eziphambili ezineenkqubo zokulawula ubushushu ezichanekileyo ziyasetyenziswa. Ngexesha lenkqubo yokunyanga ubushushu, izinga lokufudumeza, ixesha lokubamba, kunye nezinga lokuphola zonke zilawulwa ngokungqongqo ngokwendlela ethile yenkqubo. Oku kuqinisekisa ukuba ulwakhiwo lwangaphakathi lwebhloko yobunzima luyafana kwaye luzinzile, nto leyo enciphisa ngempumelelo uxinzelelo lwangaphakathi ngaphakathi kwezinto.
Ngenxa yezi nkqubo zinzima, ukungaqiniseki kokulinganisa iibhloko zobunzima beKlasi A kuncitshiswe kakhulu, kwaye ukufana kwazo kuphezulu kakhulu xa kuthelekiswa nezinye iintlobo zeebhloko zobunzima. Zibonelela ngesiseko esithembekileyo ngakumbi sokulinganisa abavavanyi bobunzima, zivumela abavavanyi bobunzima ukuba bafumane ukuchaneka okuphezulu kunye nokuzinza kwimilinganiselo yabo. Nokuba kukwimveliso yemizi-mveliso, ulawulo lomgangatho kwiilabhoratri, okanye kwicandelo lophando lwesayensi, iibhloko zobunzima beKlasi A zidlala indima ebalulekileyo nebalulekileyo, zinceda iingcali ukuba zifumane idatha yokulinganisa ubunzima echanekileyo nethembekileyo.
Ngokukhetha iibhloko zobunzima beKlasi A, abathengi banokuba nokuzithemba ngokupheleleyo ekulinganisweni kwabavavanyi babo bobunzima, beqinisekisa ukuba iziphumo zabo zovavanyo lobunzima zichanekile kwaye zihambelana, ngaloo ndlela bebonelela ngenkxaso enamandla yolawulo lomgangatho kunye nophuhliso lwemveliso yeemveliso zabo.
