Mu isi yo gukora neza no kwemeza ubuziranenge, icyuma cyo hejuru gikora nk'imwe mu bikoresho by'ingenzi cyane. Waba ushyiraho ibanze ry'ibipimo by'ibipimo, ukora akazi ko gushushanya no kugenzura, cyangwa upima ibindi bikoresho byo gupima, icyuma cyo hejuru gikora urufatiro aho ubuziranenge bushingira. Nyamara si icyuma cyose cyo hejuru cyaremwe kingana. Icyiciro cy'ubuziranenge cya plate y'ubuso ya granite kigena ubusumbane bwemewe, gusubirwamo, no kuba gikwiriye imirimo yihariye yo gupima. Gusobanukirwa aya masomo y'ubuziranenge—n'impamvu Icyiciro cya 00 ari cyo gihe cy'ubuziranenge—ni ingenzi ku muntu wese ukora mu gupima, gutunganya, cyangwa kugenzura ubuziranenge.
Iyi nkuru itanga ubuyobozi bwuzuye ku bijyanye n'amasomo yo gukoresha neza plaque ya granite, hibandwa cyane cyane ku bipimo byo mu cyiciro cya 00, kubahiriza amahame ngenderwaho, ikoreshwa mu buryo bufatika, n'ubuyobozi bwo guhitamo plaque ijyanye n'ibyo ukeneye.
Ni izihe ngero z'ubuziranenge ku masahani yo hejuru?
Amasahani yo hejuru ni ubuso bwerekana neza bukoreshwa nk'urufatiro rw'ibikorwa bitandukanye byo gupima no gushushanya. Inshingano zabo z'ibanze ni ugutanga umurongo uzwi, uhamye kandi ushobora gusubirwamo aho ibipimo bishobora kugereranywa n'ibindi. Kugira ngo uru rufatiro rube rwiza, isahani yo hejuru ubwayo igomba kuzuza ibisabwa bikomeye byo kugorora no guhagarara.
Ibyiciro by'ubunyangamugayo bigena itandukaniro ntarengwa ryemewe hagati y’ubunyangamugayo butunganye icyuma gishobora kugaragaza mu gihe kiguma mu gipimo cyacyo cyemewe. Ibi byiciro byashyizweho n'imiryango yemewe y'ubunyangamugayo kugira ngo habeho ubwumvikane n'ibipimo ku bakora n'abakoresha. Amahame abiri y'ibanze agenga ubunyangamugayo bw'icyuma cyo hejuru: ASME B89.3.7 muri Leta Zunze Ubumwe za Amerika na ISO 8512 ku masoko mpuzamahanga. Nubwo sisitemu zihariye zo gushyira mu byiciro zitandukanye gato hagati y'aya mahame, amahame shingiro n'urwego rw'ubunyangamugayo birasa muri rusange.
Uburyo bwo gushyira mu byiciro ubusanzwe bugizwe n'amanota menshi, kuva ku manota y'inganda akwiriye imirimo yo gushushanya kugeza ku manota agezweho cyane akoreshwa muri laboratwari z'ibipimo n'ibigo by'igihugu bipima. Buri manota yo hejuru agaragaza ubushobozi bwo kwihanganira ibintu no kumenya neza ibipimo, ariko kandi ikiguzi cyongerewe ndetse n'ibisabwa mu kubungabunga ibintu bisaba imbaraga nyinshi.
Ubuyobozi bw'Itsinda ry'Ubutabera Busanzwe
Gusobanukirwa imiterere y’amasomo y’ubunyangamugayo bifasha kumenya aho Icyiciro cya 00 gihuye n’uburyo busanzwe bwo gukora neza.
Icyiciro cya A (cyangwa Icyiciro cya 1) cyerekana urwego rw'ibanze rw'amasahani yo hejuru afite ubuziranenge, akwiriye gukoreshwa mu isuzuma rusange aho ibisabwa mu buziranenge biri hagati. Aya masahani akunze kuboneka mu maduka y'imashini, mu byumba by'ibikoresho, no mu nganda zikora igenzura risanzwe ry'umusaruro. Amasahani yo mu cyiciro cya A asanzwe yemerera ihindagurika ry'ubugari ripimirwa mu ijana bya milimetero.
Icyiciro cya AA (cyangwa Icyiciro cya 2) gishyira imbere ubuziranenge ku bipimo bya laboratwari n'iby'igenzura. Izi plaque zikwiriye gukoreshwa mu gupima ibintu bikomeye kandi zikora nk'ingufu z'amashami agenzura ubuziranenge. Iplaque za AA zujuje ibisabwa mu mirimo myinshi yo kugenzura inganda kandi zitanga ubuziranenge buhagije ku bushobozi bwinshi bwo kwihanganira ibintu mu nganda.
Icyiciro cya K (cyangwa Icyiciro cya B) kigaragaza ibyuma bipima byujuje ibisabwa bikomeye mu nganda. Ibi bikoresho byemejwe ko bigumana ubuziranenge bukwiriye gupima ibindi bikoresho bipima no gukora imirimo yo kugenzura neza. Ibikoresho bipima bya K bikorerwa mu buryo bukomeye kandi akenshi bisaba ibidukikije bigenzurwa neza kugira ngo bikore neza.
Icyiciro cya 00 (cyangwa Icyiciro cya 0) kigaragaza urwego rwo hejuru rw'ubuziranenge buboneka ku masahani yo hejuru ya granite. Aya masahani afite ubuziranenge buhanitse yagenewe laboratwari zipima, ibikoresho byo gupima, n'ikoreshwa aho hakenewe ubusobanuro buke bushoboka bwo gupima. Amasahani yo mu cyiciro cya 00 akorwa kandi agahabwa icyemezo mu bihe bikomeye cyane, hamwe n'ubudahangarwa bwo gupima bupimirwa muri mikoroni cyangwa hejuru yayo.
Ibisobanuro n'imiterere y'icyiciro cya 00
Icyiciro cya 00 kigaragaza igipimo cya zahabu ku masahani y’ubuso bwa granite atunganye. Gusobanukirwa icyo Icyiciro cya 00 gitandukanya amanota yo hasi bisaba gusuzuma ubushobozi bwihariye n’imiterere igena uru rwego.
Ubushobozi bwo kwihanganira uburebure bw'umusatsi wo mu cyiciro cya 00 bukabije. Dukurikije ASME B89.3.7, umupira wo mu cyiciro cya 00 ugomba kugumana ubugari bw'umusatsi butarenze miliyoni 25 za santimetero (0.000025″ cyangwa hafi mikorometero 0.63) kuri metero imwe, hamwe n'ubushobozi bwo kwihanganira uburebure bw'umusatsi bungana hakoreshejwe formula y'isano ihindagurika ku masahani manini. ISO 8512 igaragaza ibisabwa nk'ibi mu buryo bungana mu buryo bugaragara. Uru rwego rwo kugaragara bivuze ko ku buso bwose bw'isahani, ingingo zo hejuru n'izo hasi zidashobora gutandukana n'igice kirenze igice cy'ubugari bw'umusatsi w'umuntu.
Kugira ngo umuntu agere ku rwego rwo hejuru rw’icyiciro cya 00 kandi akomeze gukora neza bisaba ireme ry’inganda zikora neza kandi zigenzura ibidukikije neza. Granite igomba gutoranywa neza kugira ngo ihuze n’amabuye y’agaciro, imiterere y’ibinyampeke byiza, kandi igabanuke cyane imbere mu buryo buciriritse. Ibyiciro byo gucukura no gutunganya amabuye bigomba kwirinda gushyuha cyangwa kwangirika kw’imashini bishobora guteza ihindagurika. Amaherezo, inzira zo gusya no gusimbuza neza zigomba kugera ku buryo bungana neza mu gihe hakorwa imiterere y’ubuso ikwiye gukoreshwa mu gupima neza.
Guhagarara neza k'ubushyuhe biba ingenzi cyane kuri uru rwego rwo gupima neza. Ndetse no kwaguka guto k'ubushyuhe cyangwa guhindagurika bishobora gutuma habaho amakosa yo gupima yegereza cyangwa akarenga ubushobozi bwo kwihanganira ubushyuhe ubwabwo. Bityo, amasahani ya 00 akoreshwa muri laboratwari zigenzura ibidukikije aho ubushyuhe buguma muri ± 0.5°C cyangwa bugabanye ubushyuhe, ubusanzwe 20°C. Abakoresha bagomba kandi gutanga igihe gihagije kugira ngo amasahani agere ku buringanire bw'ubushyuhe n'ibidukikije byo gupima mbere yo kwishingikiriza ku buziranenge bwemejwe.
Impamvu Icyiciro cya 00 ari ingenzi mu ikoreshwa ry'ubuhanga
Itandukaniro riri hagati y’amakarita yo mu cyiciro cya 00 n’ay’icyiciro cya AA rishobora gusa n’iry’ubumenyi, ariko rifite ingaruka zikomeye ku mikoreshereze imwe n’imwe. Gusobanukirwa igihe ubuziranenge bw’inyongera bw’icyiciro cya 00 bukenewe—n’igihe amanota ari hasi atanga umusaruro uhagije—bifasha abanyamwuga gufata ibyemezo bihendutse by’ibikoresho bitabangamiye ubuziranenge.
Amasahani yo mu rwego rwa 00 ni ingenzi iyo isahani yo hejuru ubwayo iba isoko ikomeye y’ibipimo bidasobanutse neza mu gikorwa cyo gupima. Mu gusuzuma ibice bifite ubushobozi bwo kwihanganira ibintu mu rugero rwa mikoroni, ibitagaragara neza biva ku buso bw’ifatizo bigira ingaruka ku bushobozi rusange bwo gupima. Amasahani yo mu rwego rwa 00 agabanya uyu musaruro, bigatuma uburyo bwo gupima bukorwa neza.
Laboratwari za Metrology zikora isuzuma ry’ibindi bikoresho byo gupima, harimo mikorometero, caliper, n’ibipimo by’ibipimo, zikoresha plaque za Grade 00 nk’ibipimo ngenderwaho. Uruhererekane rw’isuzuma rusubira inyuma mu bigo by’igihugu by’isuzuma ry’ibipimo, kandi buri sano riri muri urwo ruhererekane rigomba kugira uruhare runini mu kudasobanukirwa neza. Plaque za Grade 00 zikora nk’isuzuma ry’ibipimo mu buryo bwinshi bwo gupima.
Inganda zikora ibikoresho byo mu kirere, iby’ubwirinzi n’iby’ubuvuzi akenshi zigena plaque zo mu rwego rwa 00 mu bikorwa by’igenzura rikomeye. Ikiguzi kinini cyo kutubahiriza imiterere y’ibicuruzwa muri izi nganda—aho gucika intege kw’ibice bishobora kugira ingaruka mbi—bisobanura ko ishoramari rikenewe mu bice by’ingenzi biboneka.
Ibikoresho by’ubushakashatsi n’iterambere bisunika imbibi z’ubuhanga mu gukora ibintu nabyo bigira uruhare mu byapa byo mu cyiciro cya 00. Mu gihe cyo gutegura inzira nshya cyangwa gutanga ibicuruzwa bishya, ubushobozi bwo gupima bugomba kumvikana neza, kandi icyapa cyo mu cyiciro cya 00 gikuraho ikintu kimwe mu ngengo y’imari idasobanutse neza.
