ASTM D3286-96

Standard Test Method for Gross Calorific Value of Coal and Coke by the Isoperibol Bomb Calorimeter (Withdrawn 2000)

SCOPE
1.1 This test method covers the determination of the gross calorific value of coal and coke by the isoperibol bomb calorimeter.  
1.2 The values stated in SI units are to be regarded as the standard unless otherwise designated. The values given in parentheses are for information only.  
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. For specific hazard statements, see Section 8.
