标准简介：This International Standard 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 %o (parts per thousand) and 950 %o palladium.
NOTE    This method can be used to analyse other contents of 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.
