Kwithuba elide elidlulileyo, sicaphula iitafile zokuguqula i-chinese kwi-chinese, kodwa ngexesha lokusetyenziswa kwekhemizi lezixhobo kunye nokuchaneka kwechwephesha yesampulu kunye nokuchaneka kwejometri, sifumanise ukuba kukho umahluko omkhulu phakathi kweMilinganiselo eyahlukeneyo yokuguqula. Ukongeza, akakho umntu osemgangathweni, ilizwe elahlukileyo lisebenzisa itheyibhile eyahlukileyo yokuguqula, ukuzisa ukudideka kubunzima kunye namandla okuguqula.
Ukususela ngo-1965, i-China Metrology uphando lwesayensi kunye nezinye iiyunithi ziye zaseka i-brinell, i-rockwell, iVickers kunye nexabiso elinobunzima be-rockficial rongsmer kunye nokuvavanya ubudlelwane obuhambelanayo phakathi kobunzima kunye nokungqinisisa kwemveliso. Ukuphuhliswa kweyethu "ubunzima obumnyama obumnyama kunye netheyibhile yamandla enyama" efanelekileyo kwi-9 yentsimbi kwaye ngaphandle kwebakala lentsimbi. Kumsebenzi wokungqinisisa, ngaphezu kwe-100 yamacandelo athatyathiweyo, zizonke iisampulu ezingaphezulu kwe-3,000, kwaye ngaphezulu kwe-30,000 idatha yalinganiswa.
Idatha yokuqinisekisa isasazwe kumacala omabini ejikajika, kwaye iziphumo zihambelana nokusasazwa okuqhelekileyo, oko kukuthi, ezi thebhile zokuguqula zihambelana kwaye zikhona.
Olu luhlu lokuguqula luthelekiswa ntsholongwane kunye neetheyibhile ezifanayo zokuguqula zamazwe ali-10, kwaye amaxabiso okuguqula ilizwe lethu atreyitha kumazwe ahlukeneyo.
