· ASTM D388 - Standard Classification of Coals by Rank Published by ASTM on November 1, 2019 This standard covers the classification of coals by rank, that is, according to their degree of metamorphism, or progressive alteration, in the natural series from lignite to anthracite.
More DetailsThe received moisture content shows a progressive decrease from samples DECS-24 to DECS-19 and an increase in samples PSOC-1515 and DECS-21, probably due to aerial oxidation of these two samples during handling and storage conditions. [45]
