Gwajin Hydraustatic:
Ya kamata a gwada bututun ƙarfe ta hanyar amfani da na'ura ɗaya bayan ɗaya. Matsakaicin matsin lamba na gwaji shine 20 MPa. A ƙarƙashin matsin lamba na gwaji, lokacin daidaitawa bai kamata ya zama ƙasa da 10 S ba, kuma bututun ƙarfe bai kamata ya zube ba.
Bayan Mai Amfani Ya Amince, Za a iya maye gurbin Gwajin Hydraulic da Gwajin Eddy Current ko Gwajin Magnetic Flux Leakage.
Gwajin Faɗaɗawa:
Za a yi wa bututun da diamitansu ya fi mm 22 gwaji. Bai kamata a sami gogewa a bayyane, fari, ko datti a lokacin gwajin ba.
Gwajin Fashewa:
Bisa ga buƙatun Mai Siya kuma an bayyana a cikin kwangilar, ana iya yin gwajin walƙiyar bututun ƙarfe mai diamita na waje ≤76mm da kauri na bango ≤8mm. An yi gwajin a zafin ɗaki tare da taper na 60°. Bayan walƙiyar, ƙimar walƙiyar diamita na waje ya kamata ta cika buƙatun Teburin da ke ƙasa, kuma kada kayan gwajin su nuna tsagewa ko tsagewa.
Gwajin Tauri:
Za a yi gwajin taurin Brinell ko Rockwell akan samfuran daga bututu biyu daga kowace ƙasa
