BS ISO 18632:2018

This standard BS ISO 18632:2018 Alloyed steels. Determination of manganese. Potentiometric or visual titration method is classified in these ICS categories:

• 77.140.20 Stainless steels

This document specifies a potentiometric or visual titration method for the determination of manganese content in alloyed steels.

The method is applicable to manganese mass fractions between 2 % and 25 %. Vanadium and cerium interfere with the determination. If the mass fraction of cerium in the sample is less than 0,01 %, or the mass fraction of vanadium in the sample is less than 0,005 %, the interference is negligible, otherwise theoretical corrections are necessary.
