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

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).
