Shuruudaha Imtixaanka
Tijaabada fidsan
Tuubooyinka birta ah ee dhexroorkoodu ka weyn yahay 22 mm iyo ilaa 400 mm, dhumucda gidaarkana ka weyn tahay 10 mm waa in la mariyaa tijaabada fidsan. Ka dib marka muunada la simo
Imtixaanka foorarsiga
Tuubooyinka birta ah ee leh dhexroorka dibadda oo aan ka badnayn 22 mm waa inay maraan tijaabada foorarsiga. xagal laabashadu waa 90o . Radiuska foorarsigu waa 6 jeer dhexroorka dibedda ee tuubada birta. Ka dib marka la leexiyo muunadda, wax dillaac ah ama dildilaac ah looma oggola inay ka soo baxaan muunadda.
Baaritaanka makroscopic
Tuubooyinka birta ah ee sida tooska ah loogu sameeyay birta birta ah ee joogtada ah, kooxda wax keenaysaa waa in ay dammaanad qaaddo in aanay jirin baro cadcad, wasakh ah, goobooyin hawo-hoosaadyo ah, dhejisyo dhafooreed ama lakabyo iskutallaabta aashitada ah oo la jarjaray unug macroscopic ee billet ama tuubo bir ah.
Kormeer aan burburin
Marka loo eego codsiga xisbiga dalbanaya, kaas oo markaas laga wada xaajoonayo dhinacyada sahayda iyo dalabaadka oo lagu tilmaamay heshiiska, ogaanshaha cilladda ultrasonic waxaa si gaar ah loogu samayn karaa tuubooyinka birta. Ciladda gacanta dheer ee tuubada muunada tixraaca waa inay buuxisaa shuruudaha aqbalka kormeerka kadib C8 ee ku qeexan GB/T 5777-1996.
