ASTM D167/D167M-20

Standard Test Method for Apparent and True Specific Gravity and Porosity of Lump Coke

SIGNIFICANCE AND USE
4.1 Apparent and true specific gravity, as determined by this test method, are influenced by the type of coals carbonized and the operating and preparational conditions of that carbonization, that is, charge bulk density, heating rate, and pulverization level. In turn, these properties directly influence the performance in processes using coke.
SCOPE
1.1 This test method covers the determination of apparent specific gravity (Sections 5 to 9) and true specific gravity (Sections 10 to 14) of lump coke larger than 25 mm [1 in.] size and calculating porosity (Section 15) from the specific gravity data.  
1.2 Units—The values stated in either SI units or non-SI 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.  
1.3 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.  
1.4 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.
