ASTM A519 Dhuumaha Birta
Tuubadani waxay dabooshaa dhawr darajo oo kaarboon ah iyo tuubo farsamaysan oo birta daawaha ah, ha ahaato mid kulul ama qabow dhammaatay.Birta loo isticmaalo tuubada makaanikada waxaa laga yaabaa in lagu tuuro godad ama waxa laga yaabaa in lagu shubo.Marka birta darajooyinka kala duwan si isdaba joog ah loo shubay, aqoonsiga alaabta kala guurka ee natiijada ayaa loo baahan yahay.Tuubbooyinka aan kala go'a lahayn waa badeeco tuubo ah oo la sameeyay iyada oo aan lahayn tol alxan.Caadi ahaan waxaa lagu soo saaraa birta shaqaynaysa kulul, iyo haddii loo baahdo, iyadoo la qaboojiyey dhamaystirka alaabta tuubada kulul ee ka shaqeysa si ay u soo saarto qaabka, cabbirka iyo sifooyinka la doonayo.
Tuubooyinka waa in lagu dhejiyaa qaababka soo socda: wareegsan, labajibbaaran, leydi iyo qaybo gaar ah.Falanqaynta kulaylka waa in la sameeyaa si loo go'aamiyo boqolleyda walxaha la cayimay.Haddii hababka dhalaalidda labaad la isticmaalo, falanqaynta kulaylka waa in laga helaa hal xabbo oo la dhalaaliyay ama wax soo saarka hal dhalaali ah oo dhalaal kasta oo hoose ah.Tuubada waa in lagu dahaadhaa filim saliid ah ka hor inta aan loo qaabayn inay dib u dhigto miridhku marka la cayimo
