Scope
This part of GB/T 1819 specifies the determination of the silica content in tin concentrates. This part is applicable to the determination method of silica content in tin concentrates. Method 1: Determination range: 0.10% to 10.00%; Method 2: Determination range: 5.00% to 20.00%. For the overlapping part of the determination range, Method 2 shall be used as the arbitration analysis method.
