Part 1 of this standard specifies in detail the determination method of moisture content in tin concentrates, which is applicable to tin concentrate samples with a moisture content range of 0.50% to 16.00%. The hot drying method is used, that is, the sample is dried in a drying oven at 105 +/- 5 ° C until constant weight, and then the moisture content is calculated according to the mass change before and after drying. The standard requires the use of a thermostatic drying oven with precise temperature control and a high accuracy analytical balance to ensure the accuracy of the determination. Sample preparations should comply with the relevant provisions of GB/T 14260.
