ASTM D167-12a

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

SIGNIFICANCE AND USE
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 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.

6.1.1 By-Product Coke—About 23 kg (50 lb) of representative pieces of coke shall be selected from the coke wharf for each
test. This is best accomplished by dividing the coke on the wharf into approximately equal areas and selecting an equal number
of pieces from each area. Each piece of coke selected shall be approximately equal in length to one half of the width of the coke
ovens, and shall show a “cauliflower” end produced at the walls of the ovens, and an “inner” end produced at the center of the
ovens.
