Igipimo cy'ubukana ni igikoresho cyo gupima ubukana bw'ibikoresho. Dukurikije ibikoresho bitandukanye bipimwe, igipimo cy'ubukana gishobora gukoreshwa mu nzego zitandukanye. Hari ibikoresho bimwe na bimwe bipima ubukana bikoreshwa mu nganda zitunganya imashini, kandi ahanini bipima ubukana bw'ibikoresho by'icyuma. Urugero: Igipimo cy'ubukana cya Brinell, Igipimo cy'ubukana cya Rockwell, Igipimo cy'ubukana cya Leeb, Igipimo cy'ubukana cya Vickers, Igipimo cy'ubukana bwa micro, Igipimo cy'ubukana cya Shore, Igipimo cy'ubukana cya Webster n'ibindi. Imiterere yihariye y'ibi bikoresho ni iyi ikurikira:
Igipimo cy'ubukana bwa Brinell:Ikoreshwa cyane cyane mu gupima ubukana bw'icyuma gikozwe mu byuma bicuzwe n'icyuma gikozwe mu byuma bifite imiterere idahuye. Ubukana bwa Brinell bw'icyuma gikozwe mu byuma bicuzwe n'icyuma cy'umukara bufitanye isano ryiza n'ikizamini cyo gukurura. Ikizamini cyo gukomera cya Brinell gishobora kandi gukoreshwa ku byuma bidafite feri n'icyuma cyoroshye. Indabyo nto y'umurambararo w'umupira ishobora gupima ingano nto n'ibikoresho byoroshye, kandi igapima amaduka atunganya ubushyuhe n'amashami agenzura uruganda rw'inganda zitandukanye z'imashini. Ikizamini cyo gukomera cya Brinell gikoreshwa cyane mu kugenzura ibikoresho fatizo n'ibicuruzwa byarangiye. Kubera ko bicuzwe cyane, muri rusange ntigikoreshwa mu kugenzura ibicuruzwa byarangiye.
Igipimo cy'ubukana bwa Rockwell:Gerageza ibyuma bitandukanye bya fer n'ibitari fer, gerageza ubukana bw'icyuma cyazimye, icyuma cyazimye kandi gishyushye, icyuma cyakuweho, icyuma gikonjeshejwe, amasahani afite ubunini butandukanye, ibikoresho bya karubide, ibikoresho by'icyuma cy'ifu, irangi rishyushya, irangi rikonjeshwa, irangi rishobora guhindurwa, aloyide za aluminiyumu, icyuma gifata, amasahani y'icyuma yoroshye, nibindi.
Igipimo cy'ubukomere bwa Rockwell cyo hejuru:Byakoreshejwe mu gupima ubukana bw'icyuma gito, umuyoboro muto wo ku rukuta, icyuma gikomeye n'ibice bito, aloyi ikomeye, karubide, icyuma gikomeye, icyuma gikomeye, icyuma cyazimye kandi gishyushye, icyuma gikonje, icyuma gishongeshejwe, aluminiyumu, umuringa, manyeziyumu n'ibindi byuma bya aloyi.
Isuzuma ry'ubukana bwa Vickers: gupima ibice bito, ibyuma bito, impapuro z'icyuma, impapuro za IC, insinga, imiterere yoroheje ikomeye, imiterere y'amashanyarazi, ikirahure, imitako n'ibumba, ibyuma bya ferrous, ibyuma bidafite ferrous, impapuro za IC, irangi ryo hejuru, ibyuma bya laminated; ikirahure, ibumba, agate, amabuye y'agaciro, nibindi; isuzuma ry'ubukana n'uburebure bw'imiterere y'imiterere y'imiterere ya karuboni n'imiterere y'imiterere ikomeye. Gutunganya ibikoresho, inganda z'ikoranabuhanga, ibikoresho by'ibumba, inganda z'amasaha.
Knoopikizamini cy'ubukomere:ikoreshwa cyane mu gupima ubukomere bw'udukoko duto n'utworoshye, irangi ryinjira mu buso n'izindi ngero, no gupima ubukomere bwa Knoop bw'ibikoresho byoroshye n'ibikomeye nk'ibirahure, keramike, agate, amabuye y'agaciro y'ubukorano, n'ibindi, urwego rukoreshwa: uburyo bwo kuvura ubushyuhe, carburizing, quenching layer, irangi ry'ubuso, icyuma, ibyuma bidafite feri n'ibice bito n'ibito, nibindi.
Igipimo cy'ubukana bwa Leeb:icyuma n'icyuma gikozwe mu cyuma, icyuma gikozwe mu cyuma, icyuma cy'umukara, icyuma gikozwe mu cyuma ...
Shamabuye y'agaciroikizamini cy'ubukomere:Ikoreshwa cyane cyane mu gupima ubukana bwa pulasitiki yoroshye n'umukara usanzwe w'ubukana, nka rabu yoroshye, rabu y'ubukorikori, imigozi ya rubu yo gucapa, elastomer ya thermoplastic, uruhu, nibindi. Ikoreshwa cyane mu nganda za pulasitiki, inganda za rubu n'izindi nganda za shimi, harimo ubukana bwa pulasitiki ikomeye n'umukara ukomeye, nka resine ikomeye ya thermoplastic, ibikoresho byo hasi, imipira yo gutembera, nibindi. Ikwiriye cyane gupima ubukana bwa rabu n'ibikoresho bya pulasitiki birangiye aho hantu.
Igipimo cy'ubukana bwa Webster:byakoreshejwe mu gupima aloyi ya aluminiyumu, umuringa woroshye, umuringa ukomeye, aloyi ikomeye cyane ya aluminiyumu n'icyuma cyoroshye.
Igipimo cy'Uburimbane bwa Barcol:Byoroshye kandi byoroshye, iki gikoresho cyabaye icyitegererezo mu igerageza ry’ibikoresho fatizo mu murima cyangwa mu bikoresho fatizo, nk’imbaho za fiberglass, pulasitiki, aluminiyumu n’ibindi bikoresho bifitanye isano. Iki gikoresho cyujuje ibisabwa n’Ishyirahamwe ry’Abanyamerika rishinzwe kurengera inkongi z’umuriro NFPA1932 kandi gikoreshwa mu gupima ingazi z’umuriro mu murima mu bushyuhe bwinshi. Ibikoresho bipima: aluminiyumu, aluminiyumu, ibyuma byoroshye, pulasitiki, fiberglass, urwego rw’umuriro, ibikoresho bivanze, kabutike n’uruhu.
