GB/T 38145-2019 High content precious metals jewellery alloys—Determination of gold,platinum and palladium—Difference method using inductively coupled plasma optical emission spectroscopy
Abstract
This standard specifies the method of determining the content of impurity elements in high-content precious metal alloy jewelry by using inductively coupled plasma optical emission spectrometry (ICP-OES) to determine the gold content in gold alloy jewelry, the platinum content in platinum alloy jewelry, and the palladium content in palladium alloy jewelry.
This standard is applicable to precious metal alloy jewelry and precious metal alloys with a content of 995.0‰~999.9‰.
