Qeybaha darajooyinka, guryaha farsamada iyo faahfaahinta wax soo saarka waxaa xukuma noocyo badan oo heerar caalami ah iyo qaran ah oo loogu talagalay birta aan caadiga ahayn. In kasta oo AISIT-da old Aisit sedex nambar nambarka birta ee birta ah (tusaale ahaan 304 iyo 316) wali waxaa loo isticmaalaa kala-saaridda darajooyin bir ah oo birta ah, nidaamyada cusub ee kala-soocidda.
Nidaamyadan waxaa ka mid ah 1-xaraf + 5-nambar aan lahayn lambar, sida s304400, sida lagu qeexay sae iyo ASTM. Wadamada Yurub waxay qaadayaan heerarka caadiga ah ee aan la qorin Euro ee loo yaqaan Euro. Wadamadan ayaa labaduba beddelaya ama laqabsanaya heerarkooda gaarka ah ee dalkooda si ay u garaacaan heerarka caadiga ah ee euro. Qaab-dhismeedka kale ee lagu beddelo waxaa ka mid ah kuwa duugga ah ee gaboobay iyo tirooyinka sida 304s31 iyo 58e.
Darajooyinka qaarkood kuma daboolo nambarada caadiga ah waxayna noqon karaan fasallo saamiyeed ama lagu magacaabi karaa iyadoo la adeegsanayo heerarka alaabada takhasuska leh sida silsiladda alxamiska.
Heerarka birta ee birta ah ayaa si faahfaahsan loogu sharaxay Tilmaanta Itelaadeed ee British-ka ee British-ka "Tilmaanta Tilmaanta Birta ee Birta Naafada ah", oo sidoo kale loo yaqaan BSSA "buluug".
Jadwalka hoose wuxuu liis gareeyaa heerar badan oo bir ah oo bir ah, magacooda 'BS', oo ah nambarka cusub ee aan badnayn iyo magacyada cusub ee magaca.
