Esikhathini eside esidlule, sicaphuna amatafula angaphandle okuguqulwa ku-Chinese, kepha ngesikhathi sokusetshenziswa, ngenxa yokwakheka kwamakhemikhali, ubuchwepheshe be-geometric, sitholakale ukuthi kunomehluko omkhulu phakathi kwamanani ahlukahlukene wokuguqula. Ngaphezu kwalokho, ayikho indikili enobunye, izwe elihlukile sebenzisa ithebula elihlukile lokuguqula, okuletha ukudideka kobulukhuni kanye namanani wokuguqula amandla.
Kusukela ngo-1965, i-China Metrology Science Research namanye amayunithi asungule iBrinell, Roclell, amaVicker kanye nobunzima be-RocKwell Hurnness Benchmarks futhi aphoqe ngobuhlobo obukhulu bokuhlolwa kanye nokuhlola ubudlelwane obuhambisanayo phakathi kobulukhuni obuhlukahlukene, ngokuqinisekiswa kokukhiqizwa. Kuthuthukiswe "ubunzima bensimbi emnyama yensimbi kanye netafula lokuguqula amandla" elilungele uchungechunge lwensimbi engu-9 futhi kungakhathalekile kungakhathalekile ibanga lensimbi. Emsebenzini wokuqinisekisa, amayunithi angaphezu kwe-100 abamba iqhaza, kusetshenzwe amasampula angaphezu kuka-3,000, futhi kwalinganiswa idatha engaphezu kuka-30,000.
Idatha yokuqinisekisa isatshalaliswa ngokulinganayo ezinhlangothini zombili zejika lokuguqulwa, futhi imiphumela ngokuyisisekelo ihambisana nokusatshalaliswa okujwayelekile, okungukuthi, lezi zibhebhe zokuguqula zihambisana neqiniso futhi zitholakala.
Lezi zibhebhe zokuguqula ziqhathaniswe namatafula afanayo wokuguqula amazwe ayi-10, futhi amanani wokuguqulwa wezwe lethu acishe abe ngokwesilinganiso samanani wokuguqula amazwe ahlukahlukene.
