What is BS 6200-3.11.1 – Ferrous metals about?
BS 6200-3.11.1 standard is a part of the BS 6200 series that discusses the determination of cobalt for steel and cast iron using the spectrophotometric method for sampling and analysis of iron, steel and other ferrous metals. Ferrous metals such as cast and wrought iron or carbon steel are known for their tensile strength and durability.
BS 6200-3.11.1 describes a spectrophotometric method for the determination of cobalt in steel and cast iron. The method is applicable to cobalt contents from0.04 % (m/m) to 12 % (m/m).
Who is BS 6200-3.11.1 – Ferrous metals for?
BS 6200-3.11.1 on steel and cast iron applies to:
- Manufacturer of steel and iron products
- Quality testing personnel
- Ferrous metals engineer
Why should you use BS 6200-3.11.1 – Ferrous metals?
Ferrous metals such as cast and wrought iron or carbon steel are known for their tensile strength and durability. Spectrophotometry is a standard and inexpensive technique to measure light absorption or the number of chemicals in a solution. It uses a light beam that passes through the sample, and each compound in the solution absorbs or transmits light over a certain wavelength.
BS 6200-3.11.1 provides you with the principle in which the test portion is dissolved in a phosphoric-sulfuric acid mixture and oxidized with nitric acid. The reddish-brown coloured complex of cobalt with nitroso-R-salt is developed after adding sodium acetate as a buffer. BS 6200-3.11.1 also provides the determination of cobalt in steel and cast iron which includes: Preparation of the test solution, development of the colour, compensating solution and spectrophotometric measurement.
With obedience and compliance to BS 6200-3.11.1, you can efficiently provide the spectrophotometric method for the sampling and analysis of iron, steel and other ferrous metals.
