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

95.99 Withdrawal of Standard Feb 6, 2020

General information

Current stage: 95.99 Effective date: Feb 6, 2020

Originator: ISO

Owner: ISO/TC 17/SC 1

Type: International Standard

ICS: 77.080.01

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.
