Ki diferans ki genyen ant ASTM A270 ak A269?

Diferans prensipal la se ke ASTM A270 se yon estanda pou tib sanitè, pandan y ap A269 se pou tib jeneral. A270 gen kondisyon pi sevè pou fini sifas, netwayabilite, ak san pwoblèm pou satisfè bezwen endistri pharmaceutique ak manje. Nan contrast, A269 gen mwens strik kondisyon fini sifas epi li apwopriye pou aplikasyon endistriyèl plis jeneral.
