Scope
This standard specifies the method for determining the platinum content in platinum compounds. This standard is applicable to the determination of platinum content in compounds such as Pt(NH3)2(NO2)2, Pt(NH3)2Cl2, Pt(NH3)4Cl2, (NH4)2PtCl6, K2PtCl4, PtCl4, Na2PtCl6, and H2PtCl6. The measurement range is 30% to 95%.
