What is BS 1748-8 - Determination of phosphorus in copper alloys about?
BS 1748 is a British Standard on testing methods for the analysis of copper alloys.
BS 1748-8 is the eighth part of the BS 1748-8 series that discusses the determination of phosphorus using the photometric method for the analysis of copper alloys. Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best-known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead.
Who is BS 1748-8 - Determination of phosphorus in copper alloys for?
BS 1748-8 on copper alloys applies to:
- Manufacturer of copper and copper alloys
- Phosphorus manufacturers
- Product design engineers
- Quality testing personnel
Why should you use BS 1748-8 - Determination of phosphorus in copper alloys?
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 1748-8 provides the principle of phosphorus in which the sample is dissolved in a mixture of nitric and hydrochloric acids, and phosphorus is converted into orthophosphoric acid. Phosphovanadomolybdic acid is subsequently formed, and the yellow colour is measured photometrically.
BS 1748-8 gives you the method with a range of up to 1.20 per cent phosphorus. This helps you in the analysis of copper alloys. BS 1748-8 exemplifies phosphorus using the photometric method for the analysis of copper alloys.
