Kwixesha elide elidlulileyo, sicaphula iitafile zokuguqulwa kwamanye amazwe ukuya kweyaseTshayina, kodwa ngexesha lokusetyenziswa, ngenxa yokwakheka kweekhemikhali zezinto, iteknoloji yokucubungula, ubungakanani bejometri yesampulu kunye nezinye izinto kunye nokuchaneka kwezixhobo zokulinganisa kumazwe ahlukeneyo, ubudlelwane bokuguqulwa kobunzima kunye namandla ukuseka isiseko kunye neendlela zokucubungula idatha zahlukile, sifumanise ukuba kukho umahluko omkhulu phakathi kwamaxabiso ahlukeneyo okuguqulwa. Ukongeza, akukho mgangatho udibeneyo, amazwe ahlukeneyo asebenzisa itafile yokuguqulwa eyahlukileyo, nto leyo ezisa ukudideka kumaxabiso okuguqulwa kobunzima kunye namandla.
Ukususela ngo-1965, iChina Metrology Scientific Research kunye nezinye iiyunithi ziye zaseka iBrinell, Rockwell, Vickers kunye neRockwell hardness benchmarks kunye ne-force values ezisekelwe kuvavanyo oluninzi kunye nophando lohlalutyo, ukuze kuhlolwe ubudlelwane obuhambelanayo phakathi kobunzima obahlukeneyo kunye namandla eentsimbi ze-ferrous, ngokuqinisekiswa kwemveliso. Siphuhlise "itafile yethu yokuguqula ubunzima bentsimbi emnyama kunye namandla" efanelekileyo kwiintsimbi ezili-9 kwaye kungakhathaliseki ukuba zeziphi na iintsimbi. Kumsebenzi wokuqinisekisa, iiyunithi ezingaphezu kwe-100 zathatha inxaxheba, iisampulu ezingaphezu kwama-3,000 zacutshungulwa, kwaye idatha engaphezulu kwama-30,000 yalinganiswa.
Idatha yokuqinisekisa isasazwa ngokulinganayo kumacala omabini e-conversion curve, kwaye iziphumo zihambelana ngokusisiseko nokusasazwa okuqhelekileyo, oko kukuthi, ezi tafile zokuguqulwa ngokusisiseko zihambelana nenyani kwaye zifumaneka.
Ezi theyibhile zokuguqulwa ziye zathelekiswa kwihlabathi liphela neetheyibhile zokuguqulwa ezifanayo zamazwe ali-10, kwaye amaxabiso okuguqulwa kwelizwe lethu aphantse abe ngumyinge wamaxabiso okuguqulwa kwamazwe ahlukeneyo.
