**What is BS 1728-15 – Aluminium and aluminium alloys about?**

BS 1728-15 standard is a part of the BS 1728 series that discusses the determination of nickel using the photometric method for the analysis of aluminium and aluminium alloys. Aluminium alloys are widely used in engineering structures and components requiring lightweight or corrosion resistance.

**Who is BS 1728-15 – Aluminium and aluminium alloys for?**

BS 1728-15 on aluminium alloys applies to:

Manufacturer of aluminium alloys
Quality testing personnel
Designing engineers
Aerospace engineer

**Why should you use BS 1728-15 – Aluminium and aluminium alloys?**

Aluminium alloys are widely used in engineering structures and components requiring lightweight or corrosion resistance. 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 1728-15 provides you with the principle of nickel using the photometric method in which the alloy is dissolved in sodium hydroxide solution and the insoluble material containing the nickel is dissolved in acid. The optical density of this solution is then measured at about 445 mÈ. This helps you in analysing aluminium and aluminium alloys.

BS 1728-15 exemplifies nickel using the photometric method for the analysis of aluminium and aluminium alloys.
