What is BS 3338-18 – Tin and tin alloys about?
BS 3338-18 standard is a part of the BS 3338 series that discusses the determination of aluminium using the photometric method for the sampling and analysis of tin and tin alloys. Tin and tin alloys are the properties of tin making 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 3338-18 – Tin and tin alloys for?
BS 3338-18 on tin alloys applies to:
- Manufacturer of metal products
- Quality testing products
- Design engineers
Why should you use BS 3338-18 – 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.
BS 3338-18 provides you with the principle in which the aluminium is determined photometrically with chrome-azurol S after the removal of interfering elements. This method is recommended for tin contents up to 0.05 per cent aluminium. This helps you in the sampling and analysis of tin and tin alloys.
BS 3338-18 exemplifies the aluminium in solders and white metal bearing alloys using the photometric method for the sampling and analysis of tin and tin alloys.
