① Mefuta ea thepa e sebetsang: E ​​loketse haholo lisebelisoa tse thata joalo ka li-carbides tse samenteng, tšepe le tšepe. E boetse e loketse litšepe tse se nang ferrous tsa boima bo bohareng.

② Maemo a tloaelehileng a ts'ebeliso: Ho etsa le ho laola boleng ba lisebelisoa tsa carbide tse entsoeng ka samente le hlobo. Teko ea boima ba likarolo tsa mochini le likarolo tsa sebopeho. Tlhahlobo ea tšepe e entsoeng ka tšepe le tšepe.

③ Likarolo le melemo: Mefuta e mengata ea lits'ebetso: Sekala sa HRK se loketse lisebelisoa ho tloha ho tse mahareng ho isa ho tse thata, ho fana ka tlhahlobo e nepahetseng ea boima. Mojaro o phahameng: Sebelisa mojaro o phahameng (150 kg), o loketseng lisebelisoa tse nang le boima bo phahameng, ho netefatsa ho nepahala ha liphetho tsa liteko. Ho pheta-pheta ho phahameng: Indenter ea bolo ea tšepe e fana ka liphetho tse tsitsitseng le tse phetoang haholo.

④ Lintlha kapa meeli: Tokiso ea mohlala: Sebaka sa sampole se hloka ho ba se bataletseng le ho hloeka ho netefatsa bonnete ba liphetho tsa tekanyo. Meeli ea lintho tse bonahalang: Bakeng sa thepa e thata ka ho fetisisa kapa e bonolo, HRK e ka 'na ea se ke ea e-ba khetho e nepahetseng ka ho fetisisa, hobane indenter ea bolo ea tšepe e ka' na ea hatella haholo kapa ea hatella sampuli, e leng se hlahisang liphello tse sa nepahalang tsa tekanyo. Tlhokomelo ea lisebelisoa: Thepa ea liteko e hloka ho lekanyetsoa le ho hlokomeloa khafetsa ho netefatsa bonnete le ts'epahalo ea tekanyo.
