Scope
This document specifies the method for determining the lead content in tungsten concentrates. This document is applicable to the determination of lead content in tungsten concentrates and includes two methods (Method I: Hydride Generation Atomic Fluorescence Spectrometry; Method II: Flame Atomic Absorption Spectrometry). The determination range (mass fraction) of Method I is 0.001% to 0.30%; the determination range (mass fraction) of Method II is 0.10% to 0.50%. The overlapping part of the determination range shall be subject to Method II as the arbitration method.
