标准简介：This International Standard describes a method for the determination of platinum in platinum jewellery alloys,
preferably within the range of fineness specified in ISO 9202, by means of inductively coupled plasma (ICP)
emission spectrometry.
The preferred platinum content of the alloys lies between 850 %o (parts per thousand) and 950 %~ platinum.
NOTE This method can be used to analyse other contents of platinum.
Platinum 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.
