Uma uxhuma-izixhumi zohlobo lwe-N, kubalulekile ukukhetha izintambo ezifanele futhi uqinisekise ukuhambisana kwazo ngaphambi kokuxhuma. Ukuqinisekisa ukuthi i-crimp enhle kubalulekile ekusebenziseni isixhumi ngokuphumelelayo. Ngakho-ke, yimiphi imininingwane okufanele icatshangelwe lapho kufakwa-izixhumi zohlobo luka-N?
1. Ngemva kokuxhuma, hlola ukubukeka ukuze uqinisekise ukuthi konke kulungile ngaphambi kokudlulela esinyathelweni esilandelayo. Izinto zokuhlola zizohluka kuye -ngemodeli yesixhumi sohlobo lwe-N.
2. Uma ukhubaza-izixhumi zohlobo lwe-N, qinisekisa ubude obufanele bokuvala kanye nokubekwa okufanele. Akufanele kube neziphetho zezintambo eziphumela kusixhumi se-crimp, futhi umfutho womoya kufanele ugcinwe ngaphakathi kwebanga elishiwo.
3. Ngesikhathi se-crimping ezenzakalelayo, zonke izingxenye kufanele zisebenze kahle, izixhumi kufanele zihambisane ngokunembile, futhi izintambo kufanele zigcine ukungezwani okufanele.
4. Ubukhulu besixhumi nezintambo kufanele buhlangabezane nezindinganiso ezifanele, njengoba kushiwo ngokucacile encwadini yeziqondiso.
