ASTM D167-12a

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.

1.1 This test method covers the determination of apparent specific gravity (Sections 2 to 9) and true specific gravity (Sections 10 to 13) of lump coke larger than 25-mm (1-in.) size and calculating porosity (Section 14) from the specific gravity data.

1.2 The values given in SI units shall be regarded as the standard. Inch-pound units shall be accepted on an equivalent basis.

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 and health practices and determine the applicability of regulatory limitations prior to use.
