Imtixaanka Flatten
Tuubbooyinka birta leh oo leh dhexroor ka weyn 22 mm oo ilaa 400 mm ah, iyo dhumucda darbiga ka weyn 10 mm waa in la maraa tijaabada furaha. Ka dib markii shaybaarka la jajabiyo
Tijaabinta casaanka
Tuubbooyinka birta leh oo leh dhexroor banaanka ah oo aan ka badnayn 22 mm waa in la maraa tijaabada foosha. Xagalka foosha waa 90o. Radius foornada waa 6 jeer dhexroorkii dibedda ee tuubbada tuubbada birta.
Imtixaanka Macroscopic
Tuubbooyinka birta si toos ah ayaa loo sameeyaa biilasha si isdaba joog ah ama xisbiyada birta, xisbiga keenida, wasakhda hawada, jaranjarada buugga, unugyada iskutallaabta ah ee loo yaqaan 'mucroscopic-ka' ee loo yaqaan 'biillet'.
Baadhitaan aan dumin karin
Sida ku xusan codsigii xisbiga dalbaday, kaas oo markaa ka dib lagala xaajooday inta udhaxeysa qeybinta iyo xisbiyada ku saabsan heshiiska, ogaanshaha cilad xagga ciladaha ah ee ultrasonic ayaa laga yaabaa in si gaar ah loo sameeyo tuubooyinka birta. Cilladaha Londitidaininininal ee tubada tubada tixraaca waa inuu buuxiyaa shuruudaha aqbalaadda kormeerka ka dib ee aqbalaadda fasalka C8 ee lagu cayimay GB / T 5777-1996.
