标准范围

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.NOTEThis method can be used to analyse other contents of palladium.Palladium jewellery alloys can contain silver, indium, gallium, copper, cobalt, nickel, tin and ruthenium. Thepresence of these alloying elements has not been observed to interfere with the determination method. Ifother elements are alloyed, a check is made as to whether any interference occurs.
