GB/T 15072.8-2008 Test method of precious metal alloys—Determination of copper content for gold, palladium and silver alloys—Complexometric return titration using thiourea releasing EDTA
Abstract
This section specifies the method for determining the copper content in gold, palladium, and silver alloys. This section is applicable to the determination of copper content in AuAgCu, AuAgCuGd, AuCuNiZn, AuCuNiZnMn, PdAgCu, PdAgCuAuPtZn, AgCu, AgCuV, and AgCuNiAl alloys. The measurement range (mass fraction): 4% to 35%.
