ActiveNondestructive mensuration of gold content in the gold products - Part 1: Method of electron probe microanalysis
黄金制品金含量无损测定方法 第1部分：电子探针微分析法
Application Summary AI generated
This standard specifies a nondestructive method for measuring the gold content in gold products using electron probe microanalysis (EPMA). It is applied in the jewelry and precious metals industries for quality control, certification, and appraisal of finished gold items such as coins, bars, and ornaments, where preserving the sample's integrity is essential. The method is particularly useful for testing small, valuable, or uniquely shaped gold products that cannot be subjected to destructive chemical analysis.
