ASTM D3176-24
(Practice)Standard Practice for Ultimate Analysis of Coal and Coke
Standard Practice for Ultimate Analysis of Coal and Coke
SIGNIFICANCE AND USE
4.1 Summarizing the ash mass fraction and the mass fraction of the organic constituents in a specific format under the heading, Ultimate Analysis, provides a convenient and uniform system for comparing coals or cokes. This tabulation used with that of Proximate Analysis (Practice D3172) permits cursory valuation of coals for use as fuel or in other carbonaceous processes and of cokes for metallurgical purpose.
SCOPE
1.1 This practice covers the term ultimate analysis as it is applied to the analysis of coal and coke. The information derived is intended for the general utilization by applicable industries, to provide the basis for evaluation, beneficiation, or for other purposes.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.2.1 All percentages are percent mass fractions.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions:
3.1.1 ultimate analysis—in the case of coal and coke, the determination of carbon, hydrogen, nitrogen, and sulfur in the material,
as found in the gaseous products of its complete combustion, the determination of ash in the material as a whole, and the
calculation of oxygen by difference.
NOTE 1—Moisture is not by definition a part of the ultimate analysis of coal or coke but must be determined in order that analytical data may be converted
to bases other than that of the analysis sample.
NOTE 2—Inasmuch as some coals contain mineral carbonates, and practically all contain clay or shale containing combined water, a part of the carbon,
hydrogen, and oxygen found in the products of combustion may arise from these mineral components.
