What is BS 3338-8 – Tin and tin alloys about?
BS 3338-8 standard is a part of the BS 3338 series that discusses the determination of bismuth 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 3338-8 – Tin and tin alloys for?
BS 3338-8 on tin alloys applies to:
- Manufacturer of metal products
- Quality testing personnel
- Design engineers
Why should you use BS 3338-8 – Tin and tin alloys?
Bismuth is thus a useful component of type-metal alloys, which make neat, clean castings; and it is an important ingredient of low-melting alloys, called fusible alloys, which have a large variety of applications, especially in fire-detection equipment. 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 3338-8 provides you with the principle in which the bismuth is determined photometrically with thiourea after the removal of tin and antimony as bromides in the presence of perchloric acid. This method is recommended for bismuth-containing ranges up to 0.07 per cent bismuth. This method helps you in the sampling and analysis of tin and tin alloys.
BS 3338-8 exemplifies the bismuth using the photometric method for the analysis of tin and tin alloys.
