ISO 589:2003 describes two methods for the determination of the total moisture content of hard coals. Depending on the coal rank, there may be systematic differences between the results obtained by applying different methods on subsamples of the same sample. Methods using a nitrogen atmosphere are suitable for all hard coals; methods with drying in air are only suitable for hard coals not susceptible to oxidation.
