Amapuleti okulinganisa ama-Granite angamathuluzi abalulekile onjiniyela bokunemba nokwenza, ukuhlinzeka indawo ezinzile futhi enembile yokulinganisa nokuhlola izinto. Ukuqinisekisa ukuthembeka nokusebenza kwabo, amazinga ahlukahlukene embonini kanye nezitifiketi zilawula ukukhiqizwa kanye nokusebenzisa la mapuleti okulinganisa.
Enye yezindinganiso eziphambili zamapuleti okulinganisa ama-granite yi-ISO 1101, echaza ukucaciswa komkhiqizo wejometri (i-GPS) kanye nokubekezelelana kwamathuluzi wokulinganisa. Leli Zinga liqinisekisa ukuthi amapuleti ama-granite ahlangabezana nokufundwa okuthile nezidingo zokuqeda indawo, okubalulekile ukuze uzuze izilinganiso ezinembile. Ngaphezu kwalokho, ukulinganisa ama-granite abakhiqizi bepuleti bavame ukufuna isitifiketi se-ISO 9001, esigxile ezinhlelweni zokuphathwa kwekhwalithi, ukukhombisa ukuzibophezela kwazo kwikhwalithi kanye nokwenza ngcono okuqhubekayo.
Enye isitifiketi esibalulekile yi-ASME B89.3.1 Ejwayelekile, enikeza ukuholwa kokulinganisa nokuqinisekiswa kwamapuleti okulinganisa ama-granite. Leli Zinga lisiza ekuqinisekiseni ukuthi amapuleti okulinganisa azogcina ukunemba kwawo ngokuhamba kwesikhathi, anikeze abasebenzisi ukuzethemba ngezilinganiso ezenziwe kubo. Ngaphezu kwalokho, kubalulekile ukusebenzisa i-granite eqinisekisiwe emthonjeni odumile, njengoba ukuqina nokuqina kokuqukethwe okuthinta ngokuqondile ukusebenza kwamapuleti okulinganisa.
Ngaphezu kwalezi zindinganiso, abakhiqizi abaningi banamathela ezitingweni ezithile zezimboni, njengalezo ezivela kwiNational Institute of Standards and Technology (NITS) noma i-American National Standards Institute (ANSI). Lezi zitifiketi zinikeza isiqinisekiso esithe xaxa sokuthi amapuleti okulinganisa ama-granite ahlangabezana namazinga okusebenza aqinile futhi afanele ukusetshenziswa kwezicelo eziphezulu.
Ekuphetheni, amazinga ezimboni kanye nezitifiketi zidlala indima ebalulekile ekukhiqizweni nasekusebenziseni amapuleti okulinganisa ama-granite. Ngokunamathela kulezi ziqondiso, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ifinyelela ukunemba nokuthembela okudingekayo ukuze kuqinisekiswe ubunjiniyela, kusiza ekuthuthukiseni ukulawulwa kwekhwalithi nokusebenza okusebenzayo kuzo zonke izimboni ezahlukahlukene.
