ASTM D3176-89(2002)
(Practice)Standard Practice for Ultimate Analysis of Coal and Coke
Standard Practice for Ultimate Analysis of Coal and Coke
SIGNIFICANCE AND USE
Summarizing the ash content and the content 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 D 3172) 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 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
1.3 The values stated in SI units are to be regarded as the standard.
