Description

This European Standard specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the bismuth content of copper and copper alloys in the form of unwrought, wrought and cast products. The method is applicable to products having bismuth mass fractions between 0,01 % and 0,25 %. Principle: Dissolution of a test portion in a mixture of hydrochloric acid/hydrogen peroxide and nitric acid solutions followed, after suitable dilution, by aspiration into an air/acetylene flame of an atomic absorption spectrometer. Measurement of the absorption of the 223,1 nm line emitted by a bismuth hollow-cathode or electrodeless discharge lamp.
