Scope

This part of GB/T 26930 specifies the method for determining the moisture content in coal tar used in the production of primary aluminum.
This part is applicable to the determination of moisture content in coal tar used in the production of primary aluminum. The measurement range is 0.1% to 2.0% (mass fraction).
Note: When the water content is greater than 2.0% (mass fraction), this method can be used to test with a larger receiver.
