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.
