What is BS EN 12441-3 – Zinc and zinc alloys about?
BS EN 12441-3 standard is a part of the BS EN 12441 series that discusses the flame atomic absorption spectrometric method for zinc and zinc alloys. Zinc alloys are used for building and architectural applications such as rainwater systems, claddings, fittings and roofing.
BS EN 12441-3 specifies a flame atomic absorption spectrometry method for the determination of lead, copper and cadmium in zinc and zinc alloys. It is suitable for the determination of lead contents (mass fractions) between 0,000 5 % and 2,5 %, cadmium contents (mass fractions) between 0,000 5 % and 0,3 %, and copper mass fractions between 0,000 5 % and 4 %.
Who is BS EN 12441-3 – Zinc and zinc alloys for?
BS EN 12441-3 on flame atomic absorption spectrometric method applies to:
- Manufacturer of zinc alloy products
- Quality testing personnel
- Design engineers
Why should you use BS EN 12441-3 – Zinc and zinc alloys?
Flame atomic absorption spectrometry is a measurement of the absorption of electromagnetic radiation, emitted by an element at a determined wavelength, by an absorbent medium (flame) formed of atoms of the same element that are in the ground state. Each element absorbs radiation of specific wavelengths and the intensity of the absorbed radiation is proportional to the concentration of the said element.
BS EN 12441-3 provides you with the principle in which a sample of the metal or alloy is dissolved in a mixture of hydrochloric acid and nitric acid and, after adequate dilution and atomization of the solution into an air–acetylene flame, the content of the particular element is determined by flame atomic absorption spectrometry.
BS EN 12441-3 provides you with comprehensive guidance useful throughout the process of flame atomic absorption spectrometric method.
