Steel and iron -- Determination of total silicon content -- Gravimetric method
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
The document specifies a gravimetric method for the determination of the total silicon content in steel and iron. The method is apllicable to silicon contents between 0,10 % (m/m) and 5,0 % (m/m). For samples containing molybdenum, niobium, tantalum, titanium, tungsten, zirconium or high levels of chromium, the result are less precise than for unalloyed steels.
