Omfattning
This International Standard describes two methods for determination of the total moisture content of hard
coals, a two-stage method and a single-stage method. For either method there is a choice between drying in
air and drying in a nitrogen atmosphere. Depending on the coal rank, there may be systematic differences
between the results obtained by drying in the different atmospheres on subsamples of the same sample.
Drying in a nitrogen atmosphere is suitable for all hard coals, while drying in air is only suitable for hard coals
not susceptible to oxidation.
NOTE The term “not susceptible to oxidation” cannot be defined easily. Usually, high-rank coals such as anthracites
are not oxidized under the conditions described in this International Standard. For all other types of coal, this has to be
verified by experiments.
