ASTM D5865/D5865M-19
(Test Method)Standard Test Method for Gross Calorific Value of Coal and Coke
Standard Test Method for Gross Calorific Value of Coal and Coke
SIGNIFICANCE AND USE
5.1 The gross calorific value can be used to compute the total calorific content of the quantity of coal or coke represented by the sample for payment purposes.
5.2 The gross calorific value can be used for computing the calorific value versus sulfur content to determine whether the coal meets regulatory requirements for industrial fuels.
5.3 The gross calorific value can be used to evaluate the effectiveness of beneficiation processes.
5.4 The gross calorific value can be required to classify coals according to Classification D388.
SCOPE
1.1 This test method pertains to the determination of the gross calorific value of coal and coke by either an isoperibol or adiabatic combustion calorimeter.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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. Specific hazard statements are given in Section 8.
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.
