The principle of the method specified is dissolving the sample in dilute nitric acid and determining the silver content of the resulting solution by titration with standard potassium bromide solution, using a potentiometric indication of the equivalence point. The alloys, preferably within the range of fineness stated in ISO 9202, may contain copper, zinc, cadmium and palladium. Apart from palladium, which must be precipitated before commencing titration, these elements do not interfere with this method of determination.
