ASTM-D5515 › Standard Test Method for Determination of the Swelling Properties of Bituminous Coal Using a Dilatometer
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method specifies a procedure for the measurement of the swelling of bituminous coal using a dilatometer.
1.2 The test method is limited in applicability to those coals which have a free swelling index ≥1 as determined in accordance with Test Method D720.
1.3 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.4 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.
1.5 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.
Significance and Use
5.1 Values of the dilatation properties of coals may be used to predict or explain the behavior of a coal or blends during carbonization or in other processes such as gasification, liquefaction, and combustion.
