Resumen:
This standard describes a method for the determination of palladium in palladium jewellery alloys, prefered in the range of fineness as stated in ISO 9202. The determination is performed due inductive coupled plasma optical emmission spectrometrie (ICP-OES). The recommended palladium concentration of the alloys is between 500 promille and 950 promille palladium. This method is a referenc method for the determination of the fineness in alloys up to 990 promille, as stated in ISO 9202.
