Dry, mineral matter-free basis: Data or results are calculated to a theoretical base as if there were no moisture or mineral matter in the coal sample (ASTM method D388-12; American Society for Testing and Materials, 2013, p. 390–396). For this basis, a calculation is needed to determine mineral-matter content rather than ash yield.
