More D Ash obtained differs in composition from the inorganic constituents present in the original coal. Incineration causes an expulsion of all water, the loss of carbon dioxide from carbonates, the conversion of iron pyrites into ferric oxide, and other chemical reactions.

Ash, as determined by this test method, will differ in amount from ash produced in furnace operations and other firing systems because incineration conditions influence the chemistry and amount of the ash.

References for correcting ash results determined by this test method to a mineral-matter-free basis are listed in Classification D, Section 9. Scope 1. The results obtained can be applied as the ash in the proximate analysis, Practice D, and in the ultimate analysis, Practice D For the determination of the constituents in ash, reference is made to Test Methods D, D, and D Test Methods D should be used to prepare ash to be used for trace element analysis.

See Terminology D for definition of ash. The values given in parentheses after SI units are provided for information only and are not considered standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
