- Scope
- This document describes a method for the determination of silver content in silver alloy jewelry using the potassium bromide volumetric method (potentiometric titration). This document applies to silver alloy jewelry, handicrafts and materials with a silver content of 800‰~999‰. These silver alloys may contain copper, zinc, cadmium and palladium. Except for palladium, which should be precipitated and separated before starting the titration, the presence of other elements will not interfere with the determination method. This method is designated by GB11887 as an arbitration method for the determination of silver content in silver alloy jewelry.
