Pd is the basis.
According to GOST 31290-2005 the chemical composition is given for palladium ПдА-2 (ingots) and ПдАП-2 (in powder), the total content of all impurities is ≤ 0.10%, the total content of Pt + Ir + Rh + Ru ≤ 0.05% . In agreement with the consumer, the number of detectable elements (impurities) can be expanded and their maximum permissible mass fractions determined, as well as the determination of losses during ignition for platinum in powder according to the methods of the manufacturer. The mass fraction of silver, magnesium, zinc, copper and nickel in grade ПдА-2 is not standardized but determined by the manufacturer.
