Phawula:
I-1. I-Brinell ubunzima: Kusetyenziswa ikakhulu ukulinganisa ubulukhuni beinkcazelo, ukuxolela, iinxalenye ezingenasinyithi, ii-billets ezivuthiweyo ezishushu, ii-billets ezivuthiweyo kunye neendawo ezixineneyo. Uluhlu lwemilinganiselo yi-≥HB450.
I-2. I-Rockwell Hardy: I-HRA isetyenziselwa ikakhulu iminqweno ephezulu yobunzima bokulinganisa izixhobo kunye nobunzima obungaphezulu kwe-HRC67, njenge-DRCID, njl njl. I-HRC isetyenziselwa ukulinganisa ubunzima bamacandelo entsimbi (njengentsimbi yekharbon, intsimbi yentsimbi, intsimbi yentsimbi, njl. Njl.) Emva kokucinywa okanye ukuwacaphuka. Uluhlu lwemilinganiselo yi-HRC20 ~ 67.
3. I-Viloszzzle: isetyenziselwa ukulinganisa ubunzima bamacandelo amanqamlezo kunye neenxalenye zentsimbi zentsimbi, kwaye zinokusetyenziselwa ukulinganisa ubunzima bendawo ekhulayo, ukuwina kunye nokuzithoba.
