This value is exclusive of silver and shall be determined by the difference of the “impurity total” from 100 %. “Impurity total” is defined as the sum of antimony, arsenic,
bismuth, cadmium, iron, lead, manganese, nickel, oxygen, phosphorus, selenium, silver, sulfur, tellurium, tin, and zinc present in the sample.
