Significance and Use
4.1 The values determined in this test method indicate to what extent a given coal or coal blend will expand or contract during the carbonization process when evaluated in terms of pertinent experience with other coals and coal blends and processing conditions used in commercial-type coke ovens.
1.1 This test method covers a large-scale laboratory test for obtaining information on the expansion or contraction of coal or coal blends during carbonization under specified conditions. This test method is applicable in the examination of coals or coal blends intended for use in the manufacture of coke.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
