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.
Abstract
Overview
ISO 18632:2018 defines a laboratory method for the determination of manganese in alloyed steels using either potentiometric titration or visual titration. The standard applies to manganese mass fractions from 2 % to 25 % and specifies sample preparation, reagents, apparatus, titration procedures, standardization and calculation rules. It also addresses interferences from vanadium and cerium and gives criteria for when theoretical corrections are required.
Key topics and requirements
- Scope and applicability: Manganese content between 2 % and 25 %; vanadium and cerium can interfere. Interference is considered negligible if cerium
