O fa'avasegaga fa'asao-pa'u ua vaevaeina i la'asaga muamua mo le la'uina ma tulaga lua mo fale gaosimea. I totonu o le tulaga lua, vaega laiti e aofia ai le IIA, IIB, ma IIC, i le fa'asologa fa'aa'e o le malosi e fa'asa'o pa: IIA < IIB < IIC. The 'T' category denotes vevela vaega. A ‘T’ fua fa'atatau o lo'o fa'atumauina e le masini le vevela i lalo ole 135°C, ma le T6 o le tulaga sili ona saogalemu, fautua mo le maualalo o le vevela i luga e mafai ai.
Mulimuli ane, ua mamanuina lenei oloa pa-faamaoniga e pei o se saogalemu i totonu masini eletise, fa'amoemoe mo le fa'aoga i kasa Vasega B e le sili atu i le 135°C le vevela o luga.
