Amasahani yo gupimisha ya granite ni ibikoresho by'ingenzi mu buhanga n'inganda bigezweho, bitanga ubuso buhamye kandi bunoze bwo gupimisha no kugenzura ibice. Kugira ngo bigenzurwe neza kandi bikore neza, amahame n'ibyemezo bitandukanye by'inganda bigenga ikorwa n'ikoreshwa ry'aya masahani yo gupimisha.
Imwe mu ngingo z'ingenzi zikoreshwa ku bipimo bya granite ni ISO 1101, igaragaza ibipimo by'ibicuruzwa bya geometrike (GPS) n'uburyo ibikoresho bipimisha bipimwa bipimwa. Iyi ngingo igenzura ko ibipimo bya granite byujuje ibisabwa kugira ngo bibe birambuye kandi bitunganye, ibyo bikaba ari ingenzi kugira ngo hagerwe ku bipimo nyabyo. Byongeye kandi, abakora ibipimo bya granite bakunze gushaka icyemezo cya ISO 9001, cyibanda ku buryo bwo gucunga ubuziranenge, kugira ngo bagaragaze ko biyemeje kunoza ubuziranenge no gukomeza kunoza.
Ikindi cyemezo cy'ingenzi ni igipimo cya ASME B89.3.1, gitanga ubuyobozi bwo gupima no kugenzura amasahani yo gupimisha granite. Iri gipimo rifasha kwemeza ko amasahani yo gupimisha azakomeza kuba meza uko igihe kigenda gihita, bigatuma abayakoresha bizera ibipimo byayo. Byongeye kandi, ni ngombwa gukoresha granite yemewe iturutse ahantu hizewe, kuko ubucucike n'ubudahangarwa bw'ibikoresho bigira ingaruka zitaziguye ku mikorere y'amasahani yo gupimisha.
Uretse aya mahame, inganda nyinshi zubahiriza ibyemezo byihariye by’inganda, nk’iby’Ikigo cy’Igihugu cy’Ubuziranenge n’Ikoranabuhanga (NIST) cyangwa Ikigo cy’Igihugu cy’Ubuziranenge cy’Abanyamerika (ANSI). Ibi byemezo bitanga icyizere cy’uko ibyuma bipima granite byujuje ibisabwa mu mikorere kandi bikwiranye no gukoreshwa mu buryo bunoze.
Mu gusoza, amahame ngenderwaho n’ibyemezo by’inganda bigira uruhare runini mu gukora no gukoresha amasahani yo gupimisha granite. Mu gukurikiza aya mabwiriza, abakora bashobora kwemeza ko ibicuruzwa byabo bigira ukuri no kwizerwa bikenewe mu gukora neza, amaherezo bigafasha kunoza igenzura ry’ubuziranenge n’imikorere myiza mu nganda zitandukanye.
