What is BS 3338-17 – Tin and tin alloys about?
BS 3338-17 standard is a part of the BS 3338 series that discusses the determination of cadmium in solders and white metal bearing alloys using the photometric method for the sampling and analysis of tin and tin alloys. Tin and tin-alloy coatings are the properties of tin that make it ideal for use as a coating. Owing to the low melting point of tin, and because it readily alloys with most other metals, tin coatings can easily be produced by immersing a suitably prepared metal object in a bath of molten tin.
Who is BS 3338-17 – Tin and tin alloys for?
BS 3338-17 on tin alloys applies to:
- Manufacturer of metal products
- Quality testing personnel
- Design engineers
Why should you use BS 3338-17 – Tin and tin alloys?
Cadmium reduces the working temperature required and provides good flow properties for making the joint. Typically, 16-25% cadmium may be present in a cadmium-containing silver solder. 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 3338-17 provides you with the principle in which the cadmium is determined photometrically with dithizone after the removal of interfering elements. This method contains a range of Up to 0.12 per cent cadmium. This photometric method helps you in the sampling and analysis of tin and tin alloys.
BS 3338-17 exemplifies the cadmium in solders and white metal bearing alloys using the photometric method for the sampling and analysis of tin and tin alloys.
