Gusaba
Ikoreshwa cyane cyane mugukora ibyuma byujuje ubuziranenge bwa karubone, umuyoboro muke wo hagati wumuvuduko ukabije, umuyoboro mwinshi ushyushye utagira icyuma cya karubone
Icyiciro rusange
Urwego rwicyuma cyiza cya karubone cyubaka: 10 #, 20 #

Ibisabwa
Ikizamini
Imiyoboro y'icyuma ifite diameter yo hanze irenga mm 22 na mm 400, naho uburebure bwurukuta burenze mm 10 bugomba kwipimisha. Nyuma yicyitegererezo
Ikizamini cyo kunama
Imiyoboro yicyuma ifite diameter yo hanze itarenza mm 22 igomba kwipimisha. Inguni yunamye ni 90o. Iradiyo yunamye ikubye inshuro 6 diametero yinyuma yumuyoboro wicyuma.Nyuma yo kunama icyitegererezo, ntagice cyangwa ibice byemerewe kugaragara kurugero.
Ikizamini cya Macroscopique
Ku byuma byuma bikozwe neza na fagitire cyangwa ibyuma byinjira, uruhande rutanga isoko rugomba kwemeza ko nta bibara byera, umwanda, umuyaga mwinshi wo mu kirere, ibibyimba bya gihanga cyangwa kurambika kuri acide yambukiranya ibice bya macroscopique ya bilet cyangwa icyuma.
