- This International Standard specifies a gravimetric method for the determination of the silicon content in steels and cast irons. The method is applicable to silicon contents between 0.10% (mass fraction) and 5.0% (mass fraction). NOTE For samples containing molybdenum, niobium, tantalum, titanium, tungsten, zirconium or high levels of chromium, the results are less precise than for unalloyed steels.
