Dhuumaha lagu dalbaday sifayntan waa inay ku habboonaato foorarsiga, luminta, iyo hawlgallada la midka ah ee samaynta, iyo alxanka.Marka birta la alxanayo, waxaa loo malaynayaa in habka alxanka ee ku habboon heerka birta iyo isticmaalka ama adeegga loogu talagalay la isticmaali doono.
API 5L GR.B Dhumucda darbiga culus ee birta aan xumi lahayn waxaa lagu sameeyaa mid qabow-jiiday ama duub kulul, sida ay u baahan yihiin macaamiishu.
