Current stage: 50.20 Proof sent to secretariat or FDIS ballot initiated: 8 weeks Aug 14, 2026

Originator: ISO

Owner: ISO/TC 17/SC 1 Methods of determination of chemical composition

Type: International Standard

ICS: 77.080.01 Ferrous metals in general

Scope

The method specified is applicable to sulfur contents between 0,0003 % (m/m) and 0,010 % (m/m). However, niobium, silicon, tantalum and titanium interfere in the determination of sulfur, and application range and test portion masses of the method depend on the concentration of the interfering elements.
