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.

1. 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 The values stated in SI units () are to be regarded as 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 and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
