ISO DIS 18632

Description / Abstract: This International Standard specifies a potentiometric or visual titration method for the determination of the manganese content in alloyed steels.

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