Copper and copper alloys - Determination of silver content - Flame atomic absorption spectrometric method (FAAS)

Scope

This European Standard specifies two flame atomic absorption spectrometric methods (FAAS) for the determination of the silver content of copper and copper alloys in the form of unwrought, wrought and cast products.
The methods are applicable to products having silver mass fractions between 0,01 % and 2,0 %.
a) Method A is applicable to copper and copper alloys having silver mass fractions between 0,01 % and 1,0 % and containing antimony or tin not greater than 0,005 0 % or silicon not greater than 0,010 %.
b) Method B is applicable to copper and copper alloys having silver mass fractions between 0,01 % and 2,0 % and antimony or tin greater than 0,005 % and silicon greater than 0,010 %.
