Scope: This section specifies the method for determination of lead content in lead sulfide concentrate by precipitation of lead sulfate after acid dissolution and EDTA titration. This section applies to lead sulfide concentrates with a lead content of 50% (mass fraction) to 80% (mass fraction). This method is not applicable to lead concentrates with a barium content greater than 1% (mass fraction). This standard is an arbitration analysis method.
