This standard specifies a method for the determination of sodium content in aluminum and aluminum alloys by flame atomic absorption spectroscopy (AAS), applicable to arbitration determination of sodium content between 0.0010% and 0.50%. The standard describes in detail the dissolving process of the sample and the use of ionization inhibitors. Absorbance determination at specific wavelengths provides scientific guidance for the measurement of sodium content in aluminum and aluminum alloys.
