GB/T 15072.15-2008 Test method of precious metal alloys.Determination of nickel,zinc and manganese contents for gold,silver and palladium alloys.Inductively coupled plasma atomic emission spectrometry (English Version)
This part specifies the method for the determination of nickel, zinc and manganese in gold, silver and palladium alloys. This section applies to the determination of nickel, zinc and manganese in AuCuNiZn, AuCuNiZnMn, AuNiCr, PdAgCuAuPtZn, AuGeNi, AuGeNiCu and AuNiFeZr alloys. Measuring range (mass fraction): Ni and Zn0.5%~6%, Mn0.01%~0.5%.
