Iipleyiti zokulinganisa zegranite zizixhobo ezibalulekileyo kubunjineli obuchanekileyo kunye nokuvelisa, zibonelela ngomphezulu ozinzileyo nochanekileyo wokulinganisa nokuhlola izinto. Ukuqinisekisa ukuthembeka nokusebenza kwazo, imigangatho eyahlukeneyo yeshishini kunye neziqinisekiso zilawula ukuveliswa nokusetyenziswa kwezi pleyiti zokulinganisa.
Omnye wemigangatho ephambili yeepleyiti zokulinganisa igranite yi-ISO 1101, echaza iinkcukacha zemveliso yejometri (i-GPS) kunye nokunyamezelana kwezixhobo zokulinganisa. Lo mgangatho uqinisekisa ukuba iipleyiti zegranite ziyahlangabezana neemfuno ezithile zokuthe tyaba kunye nokugqitywa komphezulu, nto leyo ebalulekileyo ekufezekiseni imilinganiselo echanekileyo. Ukongeza, abavelisi beepleyiti zokulinganisa igranite bahlala befuna isiqinisekiso se-ISO 9001, esigxile kwiinkqubo zolawulo lomgangatho, ukubonisa ukuzinikela kwabo ekuphuculeni umgangatho kunye nokuqhubekeka.
Esinye isiqinisekiso esibalulekileyo ngumgangatho we-ASME B89.3.1, obonelela ngesikhokelo sokulinganisa nokuqinisekisa iipleyiti zokulinganisa zegranite. Lo mgangatho unceda ekuqinisekiseni ukuba iipleyiti zokulinganisa ziya kugcina ukuchaneka kwazo ngokuhamba kwexesha, zinika abasebenzisi ukuzithemba kwimilinganiselo eyenziwe kuzo. Ukongeza, kubalulekile ukusebenzisa igranite eqinisekisiweyo evela kumthombo othembekileyo, njengoko ubuninzi kunye nokuzinza kwezinto kuchaphazela ngokuthe ngqo ukusebenza kweepleyiti zokulinganisa.
Ukongeza kule migangatho, abavelisi abaninzi banamathela kwiziqinisekiso ezithile zoshishino, ezifana nezo zivela kwiNational Institute of Standards and Technology (NIST) okanye kwiAmerican National Standards Institute (ANSI). Ezi ziqinisekiso zibonelela ngesiqinisekiso esongezelelekileyo sokuba iipleyiti zokulinganisa igranite ziyahlangabezana nemigangatho yokusebenza engqongqo kwaye zifanelekile ukusetyenziswa kwizicelo ezichanekileyo.
Ukuqukumbela, imigangatho yeshishini kunye neziqinisekiso zidlala indima ebalulekileyo ekuvelisweni nasekusetyenzisweni kweepleyiti zokulinganisa zegranite. Ngokulandela le migaqo, abavelisi banokuqinisekisa ukuba iimveliso zabo zifezekisa ukuchaneka kunye nokuthembeka okufunekayo kubunjineli obuchanekileyo, ekugqibeleni kunceda ukuphucula ulawulo lomgangatho kunye nokusebenza kakuhle kumashishini ahlukeneyo.
