Abstract

This document specifies a volumetric method for the determination of silver on a material considered homogeneous. The silver content of the sample lies preferably between (100 and 999,0)聽parts per thousand (鈥�) by mass. Fineness above 999,0聽鈥� can be determined using a spectroscopy method by difference (e.g. 香港六合彩开奖 15096).

This method is intended to be used as the reference method for the determination of fineness in alloys covered by 香港六合彩开奖聽9202.
