What is BS 3907-2 - Determine iron in magnesium and magnesium alloys about?
BS 3907 is a British Standard on the testing methods for the analysis of magnesium and magnesium alloys.
BS 3907-2 is the second part of the BS 3907 series that discusses the determination of iron in magnesium alloys using the phenanthroline method for the analysis of magnesium and magnesium alloys.
Who is BS 3907-2 - Determine iron in magnesium and magnesium alloys for?
BS 3907-2 on determining iron in magnesium and magnesium alloys applies to:
- Manufacturer of magnesium and magnesium alloys
- Iron manufacturers
- Quality testing personnel
- Product design engineers
Why should you use BS 3907-2 - Determine iron in magnesium and magnesium alloys?
A rapid, accurate method for the determination of iron using hydroxylamine hydrochloride, sodium acetate buffer, and 1,10-phenanthroline is described. The ash is taken up with hydrochloric acid (1 + 1) and heated for 5 minutes. Pure aluminium is used as an alloying element in many magnesium-based alloys. In the iron and steel industry, small quantities of magnesium are added to white cast iron to transform graphite into spherical nodules, thereby significantly improving the strength and malleability of the iron.
BS 3907-2 provides you with the principle in which the sample is dissolved in hydrochloric acid and any undissolved residue is filtered off. Hydroxyammonium chloride solution is added and the ferrous 1: 10-phenanthroline colour is developed in the presence of a buffer solution. The optical density of the orange-red solution is measured at about 510 nm. This method is suitable for iron contents between 0.002–0.05 per cent.
In this regard, BS 3907-2 covers apparatus and solvent required for testing as well as test sampling and procedure to determine iron.
With BS 3907-2, you can efficiently manufacture high-quality magnesium alloys by determining the iron from it.
