ASTM D3176 – Standard Practice for Ultimate Analysis of Coal and Coke
Description:
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.
