This standard BS EN ISO 4937:2024 - TC Tracked Changes. Steel and iron. Determination of chromium content. Potentiometric or visual titration method is classified in these ICS categories:

• 77.080.01 Ferrous metals in general

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.
