This standard specifies the determination of the amount of manganese oxide by periodate oxidation photometry. This standard is applicable to the determination of manganese oxide content (calculated as MnO content) in limestone and dolomite, and is also applicable to the determination of manganese oxide content in metallurgical lime. Measuring range: the amount of manganese oxide is greater than 0.005%.
