| Significance and Use | ||||||||||||||||||||||||||||||||
|
Ash, as determined by this test method, is the residue remaining after burning the coal and coke. 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 388, Section 8. |

| 1. Scope | ||||||||||||||||||||||||||||||||
|
1.1 This test method covers the determination of the inorganic residue as ash in the analysis sample of coal or coke as prepared in accordance with Method D 2013 or Practice D 346. The results obtained can be applied as the ash in the proximate analysis, Practice D 3172, and in the ultimate analysis, Practice D 3176. For the determination of the constituents in ash, reference is made to Test Methods D 2795 and D 3682. See Terminology D 121 for definition of ash. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
