适用范围：This European Standard specifies two flame atomic absorption spectrometric methods (FAAS) for thedetermination of the silver content of copper and copper alloys in the form of unwrought, wrought and castproducts.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 %.
