    Abstract - (Show below) - (Hide below)

    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.

    Scope - (Show below) - (Hide below)

    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.
