ASTM D5515-97(2010)

Standard Test Method for Determination of the Swelling Properties of Bituminous Coal Using a Dilatometer

SIGNIFICANCE AND USE
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.
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.

Using a Dilatometer
This standard is issued under the fixed designation D5515; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
The principle of this test method is that the final volume of char obtained at the conclusion of a
standard dilatation test is dependent on the mass of coal in the coal pencil and on the radius of the
retort tube. This test method incorporates a procedure which: determines the mass of air-dried coal in
the coal pencil; provides a means to measure the average retort tube radii; and employs a means to
report coal expansion on an air dried coal weight basis.
Other test methods used to determine the swelling properties of bituminous coals include the Ruhr
(ISO 8264) and Audibert-Arnu (ISO 349) International Standard Organization (ISO) test methods.
However these two ISO test methods provide consistently different values for percent dilatation and
percent contraction. Percent contraction and dilatation values obtained using the Audibert-Arnu test
method are higher and lower respectively than those obtained using the Ruhr test method. These
differences have been attributed to trimming the length of the coal pencil from different ends. The
Audibert-Arnu test method specifies that the wider end of the coal pencil be trimmed while the Ruhr
test method specifies that the narrower end of the coal pencil be trimmed.
