Igipimo cy'ubukana bwa Brinell

Ikizamini cy'ubukomere bwa Brinell cyakozwe n'umuhanga mu by'ubukire wo muri Suwede witwa Johan August Brinell mu 1900, kikaba cyarakoreshejwe bwa mbere mu gupima ubukomere bw'icyuma.
(1) HB10/3000
①Uburyo bwo gupima n'ihame: Umupira w'icyuma ufite umurambararo wa mm 10 ushyirwa ku buso bw'ibikoresho munsi y'umutwaro wa kg 3000, kandi umurambararo w'umurambararo upimwe kugira ngo harebwe agaciro k'ubukomere.
②Amoko y'ibikoresho bikoreshwa: Bikwiriye ibikoresho by'icyuma bikomeye nk'icyuma gishongeshejwe, icyuma gikomeye, aloyi zikomeye, nibindi.
③Ingero zisanzwe zo gukoresha: Gupima ibikoresho by'imashini n'ibikoresho biremereye. Gupima ubukana bw'ibikoresho binini bicukurwamo ibyuma n'ibyuma bicukurwamo ibyuma. Kugenzura ubuziranenge mu buhanga no mu nganda.
④Ibiranga n'ibyiza: Umutwaro munini: Ukwiriye ibikoresho bikomeye kandi bikomeye, ushobora kwihanganira igitutu kinini, kandi ugatanga ibisubizo nyabyo ku bipimo. Kuramba: Icyuma gipima umupira gifite igihe kinini kandi gikwiriye gukoreshwa igihe kirekire kandi inshuro nyinshi. Uburyo bwinshi bwo gukoresha: Urashobora kugerageza ubwoko butandukanye bw'ibikoresho bikomeye by'icyuma.
⑤Icyitonderwa cyangwa imbogamizi: Ingano y'icyitegererezo: Icyitegererezo kinini kirakenewe kugira ngo harebwe ko aho icyitegererezo kiri hanini kandi ari heza, kandi ubuso bw'icyitegererezo bugomba kuba burambuye kandi busukuye. Ibisabwa ku buso: Ubuso bugomba kuba bworoshye kandi budafite umwanda kugira ngo harebwe neza ko igipimo ari ingirakamaro. Kubungabunga ibikoresho: Ibikoresho bigomba gupimwa no kubungabungwa buri gihe kugira ngo harebwe neza kandi ko ikizamini gishobora gusubiramo.
(2) HB5/750
①Uburyo bwo gupima n'ihame: Koresha umupira w'icyuma ufite umurambararo wa mm 5 kugira ngo ushyire mu buso bw'ibikoresho munsi y'umutwaro wa kg 750, hanyuma upime umurambararo w'inyongera kugira ngo ubare agaciro k'ubukomere.
②Amoko y'ibikoresho bikoreshwa: Bikoreshwa ku bikoresho by'icyuma bifite ubukana buringaniye, nk'umuringa, aluminiyumu, n'icyuma gifite ubukana buringaniye. ③ Ingero zisanzwe zo gukoreshwa: Kugenzura ubuziranenge bw'ibikoresho by'icyuma bifite ubukana buringaniye. Ubushakashatsi n'iterambere ry'ibikoresho n'ibizamini bya laboratwari. Gupima ubukana bw'ibikoresho mu gihe cyo gukora no gutunganya. ④ Ibiranga n'ibyiza: Umutwaro uringaniye: Bikoreshwa ku bikoresho bifite ubukana buringaniye kandi bishobora gupima neza ubukana bwabyo. Gukoresha byoroshye: Bikoreshwa ku bikoresho bitandukanye bifite ubukana buringaniye kandi bihindagurika cyane. Gusubiramo cyane: Bitanga ibisubizo bihamye kandi bihoraho byo gupima.
⑥Inyandiko cyangwa imbogamizi: Gutegura icyitegererezo: Ubuso bw'icyitegererezo bugomba kuba burambuye kandi busukuye kugira ngo hamenyekane neza ko ibisubizo byo gupima ari ukuri. Imbogamizi z'ibikoresho: Ku bikoresho byoroshye cyane cyangwa bikomeye cyane, hashobora gukenerwa ubundi buryo bwo gupima ubukana bukwiye. Kubungabunga ibikoresho: Ibikoresho bigomba gupimwa no kubungabungwa buri gihe kugira ngo harebwe ko ibipimo ari ukuri kandi byizerwa.
(3)HB2.5/187.5
①Uburyo bwo gupima n'ihame: Koresha umupira w'icyuma ufite umurambararo wa mm 2.5 kugira ngo ushyire mu buso bw'ibikoresho munsi y'umutwaro wa kg 187.5, hanyuma upime umurambararo w'inyongera kugira ngo ubare agaciro k'ubukomere.
②Ubwoko bw'ibikoresho bikoreshwa: Bikoreshwa ku bikoresho by'icyuma byoroshye n'ibindi bikoresho byoroshye, nka aluminiyumu, icyuma cy'ubutare, n'icyuma cyoroshye.
③Ingero zisanzwe zo gukoresha: Kugenzura ubuziranenge bw'ibikoresho by'icyuma cyoroshye. Gupima ibikoresho mu nganda z'ikoranabuhanga n'amashanyarazi. Gupima ubukana bw'ibikoresho byoroshye mu gihe cyo gukora no gutunganya.
④Ibiranga n'ibyiza: Umutwaro muke: Ikoreshwa ku bikoresho byoroshye kugira ngo hirindwe koroherwa cyane. Ishobora gusubiramo byinshi: Itanga ibisubizo bihamye kandi bihoraho byo gupima. Uburyo bwinshi bwo gukoresha: Ishobora kugerageza ubwoko butandukanye bw'ibikoresho byoroshye by'icyuma.
⑤ Inyandiko cyangwa imbogamizi: Gutegura icyitegererezo: Ubuso bw'icyitegererezo bugomba kuba burambitse kandi busukuye kugira ngo harebwe neza ko ibisubizo byo gupima ari ukuri. Inzitizi ku bikoresho: Ku bikoresho bikomeye cyane, bishobora kuba ngombwa guhitamo ubundi buryo bukwiye bwo gupima ubukana. Kubungabunga ibikoresho: Ibikoresho bigomba gupimwa no kubungabungwa buri gihe kugira ngo harebwe ko ibipimo ari ukuri kandi byizerwa.
