Sets out three methods - distillation, drying in nitrogen and drying in air - for the determination of the total moisture content of higher rank coal. A method for determination of free moisture is also included.

This Standard sets out methods for the determination of total moisture, free moisture and residual moisture in higher rank coal. The methods are as follows:(a) Drying in air, for free moisture.(b) Distillation (Method A), for residual moisture.(c) Drying in nitrogen (Method B), for residual moisture.(d) Drying in air (Method C), for residual moisture.Methods A and B are applicable to all higher rank coals. Method C is applicable only to higher rank coals that are known not to be susceptible to significant oxidation.Where the sample is visibly wet, determination of residual moisture by Method A, B or C is generally preceded by the determination of free moisture, unless the sample is suitable for the direct determination of total moisture using Method C.
