This part of this European Standard specifies a Rhodamine B spectrophotometric method for the determination of the antimony content of copper and copper alloys in the form of unwrought, wrought and cast products.The method is applicable to products having antimony mass fractions in the range between 0,001 % and 0,1 %, or greater by appropriate modification of the mass of the test portion, the volume of the test portion solution to be taken for the extraction and the cell path length.
