Steel and iron — Determination of chromium content — Indirect titration method

General information

Current stage: 50.20 Effective date: Jun 26, 2026

Originator: ISO

Owner: ISO/TC 17/SC 1

Type: International Standard

Scope

This International Standard specifies a potentiometric titration method for the determination of chromium content in
steel and iron.
The method is applicable to chromium contents between 1 % (m/m) and 35 % (m/m).
Vanadium contents in steel and iron should be less than 1 % (m/m) for chromium contents higher than 10 % (m/m)
and less than 0,2 % (m/m) for chromium contents less than 10 % (m/m).
