ISO 15355:1999 (R2022)

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).
