(Test Method)Standard Test Method for Gross Calorific Value of Coal and Coke by Microprocessor Controlled Isoperibol Calorimeters (Withdrawn 2000)
Standard Test Method for Gross Calorific Value of Coal and Coke by Microprocessor Controlled Isoperibol Calorimeters (Withdrawn 2000)
SCOPE
1.1 This test method covers the determination of the gross calorific value of coal and coke by an isoperibol bomb calorimeter using electronic temperature sensors and automatic calorimeter controllers.
1.2 The values stated in SI units are to be regarded as the standard, except as noted otherwise. The values given in parentheses are for information only. Note 1-Conversion to other units is discussed in Appendix X1. Time is expressed in minutes. Mass is expressed in grams.
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.
