Jewellery — Determination of palladium in palladium jewellery alloys — Inductively coupled plasma (ICP) solution-spectrometric method using yttrium as internal standard element ISO 11495:2008

Publication date:   Aug 7, 2008

Scope

ISO 11495:2008 describes a method for the determination of palladium in palladium jewellery alloys, preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma (ICP) emission spectrometry.
The preferred palladium content of the alloys lies between 500 ‰ (parts per thousand) and 950 ‰ palladium.
Palladium jewellery alloys can contain silver, indium, gallium, copper, cobalt, nickel, tin and ruthenium. The presence of these alloying elements has not been observed to interfere with the determination method. If other elements are alloyed, a check is made as to whether any interference occurs.
