(Test Method)Standard Test Method for Gross Calorific Value of Coal and Coke
Standard Test Method for Gross Calorific Value of Coal and Coke
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 bomb calorimeter.
1.2 The values stated in SI units are 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. Specific hazard statements are given in Section 8.
