What is BS 3338-5 – Tin and tin alloys about?
BS 3338-5 standard is a part of the BS 3338 series that discusses the determination of lead in ingot using the photometric method for the sampling and analysis of tin and tin alloys. Tin is alloyed with lead to produce solders with melting points lower than those of either tin or lead. Small amounts of various metals, notably antimony and silver, are added to tin-lead solders to increase their strength.
Who is BS 3338-5 – Tin and tin alloys for?
BS 3338-5 on tin alloys applies to:
- Manufacturer of metal products
- Quality testing personnel
- Design engineers
Why should you use BS 3338-5 – Tin and tin alloys?
Tin is alloyed with lead to produce solders with melting points lower than those of either tin or lead. Small amounts of various metals, notably antimony and silver, are added to tin-lead solders to increase their strength. 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 3338-5 provides you with the principle for lead using a photometric method in which the lead is determined photometrically with dithizone after the removal of tin as bromide. This method is recommended for lead range Up to 0.9 per cent lead. This helps you in the sampling and analysis of tin and tin alloys.
BS 3338-5 exemplifies the lead in ingot tin and tin-antimony solders using the photometric method for the analysis of tin and tin alloys.
