The principle of the method specified is dissolution of a test portion in nitric acid, measurement of the absorption of the resonance line energy from the spectrum of silver in the test solution at a wavelength of 328,1 nm by an atomic absorption spectrometer fitted with a graphite furnace electrothermal atomizer, calibration by the standard additions method described in ISO 11438-1. Applies to silver contents in the range of 1,0 g/t to 6,0 g/t in ferronickel.
