BS 3907-10 standard is a part of the BS 3907 series that discusses the determination of manganese in magnesium alloys containing zirconium, rare earth, thorium and/or silver using the photometric method. The advantage of magnesium alloys to be used in such applications is their lightweight, high strength-to-weight ratio, high stiffness-to-weight ratio, castability, machinability, and great damping.
BS 3907-10 on magnesium alloys applies to:
Manganese helps the body form connective tissue, bones, blood-clotting factors, and sex hormones. It also plays a role in fat and carbohydrate metabolism, calcium absorption, and blood sugar regulation. Manganese is also necessary for normal brain and nerve function. Photometric measurement, or photometry, is a technique that can be used to measure the concentration of organic and inorganic compounds in solution by determining the absorbance of specific wavelengths of light.
BS 3907-10 provides you with the manganese in magnesium alloys using the photometric method in which the sample is dissolved in sulphuric acid and oxidized with nitric acid. The manganous ions are oxidized to permanganic acid with potassium periodate. The optical density is measured at about 545 nm. The method is suitable for manganese contents less than 0.2 %. This helps you in the analysis of magnesium and magnesium alloys.
With obedience and compliance to BS 3907-10, you can efficiently manufacture high-quality magnesium alloys using the determination of manganese using the photometric method.
