(Test Method)Standard Test Method for Gross Calorific and Ash Value of Waste Materials (Withdrawn 2016)
Standard Test Method for Gross Calorific and Ash Value of Waste Materials (Withdrawn 2016)
SIGNIFICANCE AND USE
This test method is used to compute the calorific value and estimated ash content of the waste material represented by the sample for incineration purposes or as fuel for cement kilns.
The gross calorific and ash value may be used for evaluating the effectiveness of any beneficiation process.
SCOPE
1.1 This test method covers the determination of the gross calorific value of waste materials by either an isoperibol, aneroid, air-jacketed isoperibol, or adiabatic bomb calorimeter using electronic temperature sensors, automatic calorimeter controllers, and subsequent analysis of the residue for ash. After calorific analysis, the bomb washings may be collected for subsequent elemental analysis.
1.2 The values stated in SI units are regarded as the standard.
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.
WITHDRAWN RATIONALE
This test method covered the determination of the gross calorific value of waste materials by either an isoperibol, aneroid, air-jacketed isoperibol, or adiabatic bomb calorimeter using electronic temperature sensors, automatic calorimeter controllers, and subsequent analysis of the residue for ash.
Formerly under the jurisdiction of Committee D34 on Waste Management, this test method was withdrawn in January 2016 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
