GB/T 18996-2003
AbolishedDetermination of silver in silver jewellery alloys--Volumertic(potentiometric) method using sodium chloride or potassium chloride
银合金首饰中含银量的测定 氯化钠或氯化钾容量法(电位滴定法)
Application Summary AI generated
This standard specifies a volumetric (potentiometric) titration method using sodium chloride or potassium chloride to determine the silver content in silver jewellery alloys. It is applied in the jewellery industry for quality control and certification testing of silver alloy products, such as rings, necklaces, and bracelets, to verify compliance with purity standards. The method is particularly relevant for laboratories conducting material analysis and regulatory inspections of precious metal items.
