1 Scope
This document specifies a method for the determination of chromium in steel and iron
by potentiometric or visual titration.
The method is applicable to chromium contents between 0,25 % (mass fraction) and 35 %
(mass fraction). If vanadium is present, the visual titration is applicable only to
test portions containing less than 3 mg of vanadium.
NOTE The visual titration can be applicable to test portion containing between 3 mg and
6 mg of vanadium.
