Scope
This standard specifies the reagents, instruments and equipment, operating procedures, result calculation, and precision for determining the total moisture content in coal. The method of drying in nitrogen flow (Method A1 and Method B1) is suitable for all types of coal; the method of drying in air flow (Method A2 and Method B2) is suitable for bituminous coal and anthracite; the microwave drying method (Method C) is suitable for bituminous coal and lignite. Method A1 is used as the arbitration method.
