What is BS 3908-13 – Lead and lead alloys about?
BS 3908-13 standard is the part of the BS 3908 series that discusses the antimony using the photometric method for the sampling and analysis of lead and lead alloys. Lead alloys with metals and the principal metals are antimony, calcium, copper, tin, tellurium, and silver. The primary use of the alloys is in batteries, but other significant uses are in ammunition, cable sheeting, sheet for roofing and construction, insoluble anodes, solders, and special low melting point materials.
Who is BS 3908-13 – Lead and lead alloys for?
BS 3908-13 on lead alloys on low contents applies to:
- Manufacturer of lead alloys
- Quality testing personnel
- Designing engineers
Why should you use BS 3908-13 – Lead and lead alloys?
Even when added in minor quantities, antimony imparts strength and hardness to other metals, particularly lead, with which it forms alloys used in plates of automobile storage batteries, in bullets, in coverings for cables, and chemical equipment such as tanks, pipes, and pumps. 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 3908-13 provides you with the principle of antimony using the photometric method in which the sample is dissolved in a mixture of acetic acid and hydrogen peroxide, hydrochloric acid is added and the pentavalent antimony chloride is extracted into isopropyl ether. Rhodamine “B” is added and the determination is completed photometrically. This helps you in sampling and analysis of lead and lead alloys.
With obedience and compliance to BS 3908-13, you can efficiently manufacture high-quality lead alloys using the photometric method.
