Scope

This part of GB/T 15249 specifies the method for determining the gold content in mixed gold.
This part is applicable to the determination of gold content in mixed gold (mining gold, refined gold products, and recycled gold, etc.). The range of the gold mass fraction to be determined is 30.00% to 99.90%.
When the sample contains interfering elements (such as iridium, palladium, platinum, rhodium, ruthenium, and osmium) that affect the accuracy of the fire assay method, this part will not be applicable.
