When used in conjunction with the air dry loss moisture, as determined in accordance with Method D 2013, Test Method D 3302, or Practice D 346, the calculated total moisture can be used to convert dry basis analytical results to the asreceived basis. The result of the ash determinations can be applied in the ultimate analysis, Practice D 3176.

The total sulfur value is used for ultimate analysis. Moisture is not by definition a part of the ultimate analysis of coal but must be determined so that the analytical values obtained can be converted to bases other than that of the analysis sample. In other words, analytical values may need to be converted to an asreceived or a dry basis.
