This document specifies an analytical method for the determination of silver on a material considered homogeneous. The silver content of the samples lies preferably between 50‰ (parts per thousand) and 990‰ (parts per thousand). Fineness above 990,0‰ can be determined using a spectroscopy method by difference (see ISO15096).
NOTE Lower contents of silver can be analysed according to this method.
