BS 6721-6 standard is a part of the BS 6721 series that discusses the determination of phosphorus in copper and copper alloys by spectrophotometry for sampling and analysis of copper and copper alloys. Copper and Copper alloys are some of the most versatile engineering materials available.
BS 6721-6 specifies a molybdovanadate spectrometric method for the determination of the phosphorus content of copper and copper alloys. The method applies to the determination of phosphorus contents between 0,000 5 and 0,5 % (m/m) in all types of copper and copper alloys listed in International Standards.
BS 6721-6 on the determination of phosphorus in copper and copper alloys applies to:
Copper and Copper alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make copper suitable for a wide range of applications. Spectrophotometry is a standard and inexpensive technique to measure light absorption or the number of chemicals in a solution.
BS 6721-6 provides you with the guidance for the concentration below 0,01 % (m/m), extraction of phosphorus as phosphomolybdic acid and spectrometric determination as molybdenum blue for concentrations between 0,005 and 0,5 % (m/m), extraction and spectrometric determination as phosphovanadomolybdic acid. This helps you in the sampling and analysis of copper and copper alloys.
With BS 6721-6 you can be ensured that the products consistently meet and exceed quality assurance targets.
