Steel and iron — Determination of total silicon content — Gravimetric method

Aciers et fontes — Dosage du silicium total — Méthode gravimétrique

This edition has been replaced by ISO 439:2020.

Abstract / scope

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.
