Izakhiwo zemishini yezinto ezibonakalayo zibhekisela ezicini zemishini yezinto ezingaphansi kwendawo ehlukene (izinga lokushisa, umswakama, i-medium), ngaphansi kwemithwalo ehlukahlukene yangaphandle (ukushuba, ukucindezelwa, ukugoba, ukuxubha, umthelela, ukucindezelwa okushintshana, njll.).
Ukuhlolwa kwezakhiwo zemishini kuhlanganisa ubulukhuni, amandla kanye nobude, ukuqina komthelela, ukucindezelwa, ukugunda, ukuhlolwa kwe-torsion nokunye.
Ukuhlolwa kobulukhuni kubhekisela ku-Brinell hardness, ukuqina kwe-Rockwell, ukuqina kwe-Vickers, ukuqina okuncane; Ukuhlolwa kwamandla amandla esivuno namandla aqinile. Ukuhlolwa kwe-Tensile okusekelwe kumazinga:
Izinsimbi: GB/T 228-02, ASTM E 88-08, ISO 6892-2009, JIS Z 2241-98
Okungeyona insimbi: ASTMD 638-08, GB/T 1040-06, ISO 527-96, ASTMD 5034-09, ASTMD 638-08, GB/T 1040-06, ISO 527-96
Imishini yokuhlola esetshenziswa kakhulu yilena: umshini wokuhlola izinto ezibonakalayo, umshini wokuhlola umthelela, umshini wokuhlola ukukhathala, umhloli wokuqina we-Whole Rockwell, umhloli wokuqina we-Vickers, umhloli wokuqina ka-Brinell, umhloli wokuqina ka-Leeb.
Ukuhlolwa kwezakhiwo zensimbi kuyindlela ebalulekile ekuthuthukisweni nasekuthuthukisweni kwezinto ezintsha zensimbi, ukuthuthukisa ikhwalithi yezinto ezibonakalayo, ukukhulisa amandla ezinto ezibonakalayo (ukukhetha ukucindezeleka okufanele), ukuhlaziya ukwehluleka kwezingxenye zensimbi, ukuqinisekisa ukwakheka okunengqondo kwezingxenye zensimbi. kanye nokusetshenziswa okuphephile nokuthembekile nokugcinwa kwezakhiwo zensimbi (bheka ukucaciswa kwezakhiwo zensimbi).
Izinto zokuhlola ezijwayelekile yilezi: Ukuqina (ukuqina kwe-Brinell, ubulukhuni be-Rockwell, ubulukhuni be-Leeb, ubulukhuni be-Vickers, njll.), ukushuba kwezinga lokushisa kwegumbi, ukushuba kwezinga lokushisa eliphezulu, ukushuba kwezinga lokushisa eliphansi, ukugoba, umthelela (umthelela wezinga lokushisa, izinga lokushisa eliphansi, umthelela wokushisa ophakeme ) ukukhathala, inkomishi, umthwalo wokudweba nokudweba, inkomishi yesigaxa, ukuvuselela kabusha, ukucindezelwa, ukugunda, ukukhwehlela, ukwenza isicaba, njll. Ukuhlolwa kwezakhiwo zemishini ye-Fastener kanye nemishini yepuleti elishiselwe (ishubhu) (ukuguqulwa, ukuphuka, ukunamathela, ukukhasa, ukukhathala), njll. .
