ASTM A671 waa tuubo bir ah oo laga sameeyay saxan tayada markabka cadaadiska,Korantada-Fusion-welded (EFW)jawiga cadaadiska sare leh ee jawiga iyo heerkulka hoose.
Waxay si gaar ah ugu habboon tahay codsiyada u baahan xasilloonida cadaadiska sare iyo sifooyinka heerkulka hoose ee gaarka ah.

Kala saarista darajada
Lagu kala soocaa iyadoo loo eegayo nooca saxanka loo isticmaalo soo saarista tubooyinka birta.
Darajooyin kala duwani waxay u taagan yihiin isku-dhafka kiimikada kala duwan iyo sifooyinka farsamada ee cadaadiska iyo xaaladaha heerkulka kala duwan.
Tusaale ahaan, darajooyinka qaarkood waa birta kaarboonka ee cad, halka kuwa kalena ay yihiin birta leh walxo daawaynta lagu daray, sida birta nikkel.

Kala soocidda
Tuubooyinka waxaa loo kala soocay iyadoo loo eegayo nooca daaweynta kulaylka ee ay helaan inta lagu jiro habka wax soo saarka iyo haddii si shucaac ah loo baaro iyo in la tijaabiyo cadaadiska.
Qaybaha kala duwani waxay ka tarjumayaan sifooyinka daaweynta kulaylka ee kala duwan ee tuubooyinka.
Tusaalooyinka waxaa ka mid ah wax-ka-dhigista, ka-yaraynta walbahaarka, deminta, iyo xanaaqa.
