Ku bakiriya benshi bafite ibisabwa cyane kugira ngo ibikoresho bipima ubukana bikore neza, gupima ubukana birushaho gushimangira ubukana. Uyu munsi, nishimiye kubagezaho uruhererekane rw'ibikoresho byo mu cyiciro cya A byo gupima ubukana.—Ibikoresho byo gupima ubukana bya Rockwell, Ibikoresho byo gupima ubukana bya Vickers, Ibikoresho byo gupima ubukana bya Brinell, HRA, HRB, HRC, HRE HRR, HV, HBW n'ibindi.
Ibikoresho byo mu bwoko bwa A bifite ibisabwa bikomeye cyane mu bijyanye n'uburyo bwo gutunganya, gutunganya ubuso, no gutunganya ubushyuhe. Uburyo bwo gukora ibi bikoresho byo mu bwoko bwa hardness bukoresha uburyo buhanitse bwo gutunganya. Ahantu hagezweho ho gutunganya ibikoresho bya CNC hakoreshwa kugira ngo harebwe ko ingano z'ibikoresho byo mu bwoko bwa hardness zujuje ibisabwa neza cyane. Buri gipimo cyo gukata gihindurwa neza kugira ngo hagabanywe amakosa ashobora kubaho mu ngero.
Mu bijyanye no gutunganya ubuso, hakoreshwa uburyo bwihariye bwo kurangiza ubuso. Gusukura no gushyira ku murongo neza bikorwa kugira ngo habeho ubuso bufite ubukana buke cyane. Ibi ntibigabanya gusa kwivanga kw'ubusumbane mu gihe cyo gupima ubukana ahubwo binanongerera ihuriro hagati y'igice cy'icyuma gipima ubukana n'igice cy'icyuma gipima ubukana, bigatuma haboneka ibisubizo nyabyo ku bipimo.
Uburyo bwo gutunganya ubushyuhe bwa Class A hard blocks nabwo bugenzurwa neza. Amatanura yo gutunganya ubushyuhe agezweho afite sisitemu zo kugenzura ubushyuhe neza arakoreshwa. Mu gihe cyo gutunganya ubushyuhe, umuvuduko wo gushyushya, igihe cyo gufata, n'umuvuduko wo gukonjesha byose bigenzurwa neza hakurikijwe umurongo runaka w'uburyo bwo gutunganya. Ibi byemeza ko imiterere y'imbere y'hard block ingana kandi ihamye, bigabanura neza umuvuduko w'imbere mu bikoresho.
Kubera izi nzira zikomeye, gupima ibipimo by’ibipimo by’ubukana bw’icyiciro cya A biragabanuka cyane, kandi uburinganire bwabyo buri hejuru cyane ugereranije n’ubundi bwoko bw’ibipimo by’ubukana bw’ubukana. Bitanga ishingiro ryizewe ryo gupima ibipimo by’ubukana bw’ubukana, bigatuma ibipimo by’ubukana bw’ubukana bugera ku buziranenge n’ubudahinduka mu bipimo byabo. Haba mu nganda, mu kugenzura ubuziranenge muri laboratwari, cyangwa mu rwego rw’ubushakashatsi bwa siyansi, ibipimo by’ubukana bw’icyiciro cya A bigira uruhare runini kandi rw’ingenzi, bifasha abanyamwuga kubona amakuru nyayo kandi yizewe yo gupima ubukana bw’ubukana.
Mu guhitamo uburyo bwo gupima ubukana bw’ibicuruzwa byo mu cyiciro cya A, abakiriya bashobora kugira icyizere cyuzuye mu gupima ubukana bw’ibicuruzwa byabo, bakareba ko ibisubizo byabo byo gupima ubukana ari ukuri kandi bihuye, bityo bagatanga inkunga ikomeye mu kugenzura ubuziranenge no guteza imbere ibicuruzwa byabo.
