Tijaabada fidsanaanta
Tuubooyinka birta ah ee dhexroorkoodu ka badan yahay 22 mm ilaa 400 mm, iyo dhumucda derbiga oo ka badan 10 mm waa in la mariyo tijaabada simitaanka. Ka dib marka muunadaha la simo
Imtixaanka laabista
Tuubooyinka birta ah ee leh dhexroor dibadda ah oo aan ka badnayn 22 mm waa inay maraan tijaabada leexashada. Xagasha leexashada waa 90o. Gacanka leexashada waa 6 jibaar dhexroorka dibadda ee tuubada birta ah. Ka dib marka la foorariyo muunadda, wax dildilaac ah ama dildilaac ah looma oggola inay ka soo muuqdaan muunadda.
Baaritaanka Macroscopic-ga
Tuubooyinka birta ah ee si toos ah looga sameeyo billets si joogto ah loo shubay ama bir bir ah, qaybta bixisa waa inay hubisaa inaysan jirin dhibco cad, wasakh, xumbo hawo oo dusha sare ah, balastarro madaxeed ama lakab ku yaal unugyada macroscopic-ka ah ee aashitada iskutallaabta ah ee tuubada ama tuubada birta ah.
Kormeer aan wax burburin ah lahayn
Sida ku cad codsiga dhinaca dalbanaya, kaas oo markaa laga wada xaajoodo dhinacyada bixiya iyo kuwa dalbanaya oo lagu tilmaamay heshiiska, ogaanshaha cilladaha ultrasonic-ka ayaa si gaar ah loogu samayn karaa tuubooyinka birta ah. Cilladda gacanta ee dheer ee tuubada muunadda tixraaca waa inay buuxisaa shuruudaha heerka aqbalaadda baaritaanka kadib ee C8 ee lagu qeexay GB/T 5777-1996.
