Esikhathini eside esidlule, sicaphuna amathebula okuguqulwa kwamanye amazwe abe kwelaseShayina, kodwa ngesikhathi sokusetshenziswa, ngenxa yokwakheka kwamakhemikhali ezinto ezibonakalayo, ubuchwepheshe bokucubungula, usayizi wejometri wesampula nezinye izici kanye nokunemba kwezinsimbi zokulinganisa ezihlukahlukene. amazwe, ubulukhuni nobudlelwano bokuguqulwa kwamandla ukuze kutholwe isisekelo nezindlela zokucubungula idatha zihlukile, sithole ukuthi kunomehluko omkhulu phakathi kwamanani ahlukahlukene okuguqulwa.Ukwengeza, alikho izinga elihlanganisiwe, izwe elihlukile lisebenzisa ithebula lokuguqulwa elihlukile, okuletha ukudideka kumanani wokuqina namandla okuguqulwa.
Kusukela ngo-1965, i-China Metrology Scientific Research kanye namanye amayunithi asungule i-Brinell, i-Rockwell, i-Vickers kanye nezilinganiso zobulukhuni be-Rockwell kanye namanani aphoqelela ngesisekelo senani elikhulu lokuhlola nokucwaninga ucwaningo, ukuhlola ubudlelwano obuhambisanayo phakathi kobunzima obuhlukahlukene namandla ensimbi. izinsimbi, ngokuqinisekiswa kokukhiqiza.Sakhe "ukuqina kwensimbi emnyama kanye netafula lokuguqula amandla" elifanele uchungechunge lwensimbi engu-9 futhi kungakhathalekile ukuthi yiliphi ibanga lensimbi.Emsebenzini wokuqinisekisa, amayunithi angaphezu kwe-100 abambe iqhaza, isamba samasampula angaphezu kwe-3,000 acutshungulwa, futhi idatha engaphezu kuka-30,000 yalinganiswa.
Idatha yokuqinisekisa isatshalaliswa ngokulinganayo kuzo zombili izinhlangothi zejika lokuguqulwa, futhi imiphumela ngokuyisisekelo ihambisana nokusabalalisa okuvamile, okungukuthi, lawa mathebula okuguqulwa ngokuyisisekelo ahambisana neqiniso futhi ayatholakala.
Lawa mathebula okuguqulwa aqhathaniswe namazwe ngamazwe namathebula okuguqulwa afanayo emazweni ayi-10, futhi amanani okuguqulwa kwezwe lethu acishe abe isilinganiso samanani okuguqulwa emazweni ahlukahlukene.
