ASTM D7454-14

5.1 Vibrated bulk density (VBD) is an indicator of calcined petroleum coke porosity, which affects its suitability for use in pitch-bonded carbon applications. (1.1 This test method covers the determination of bulk density of a representative 2-kg sample of calcined petroleum coke, after vibration to increase compaction, using a semi-automatic apparatus.

1.2 The procedure is applied, but not limited, to particles passing through a 4.75-mm opening sieve and retained on a 1.18-mm opening sieve. Further, the procedure is applied, but not limited, to a specific test sample having particles passing through a 0.85-mm opening sieve and retained on a 0.425-mm opening sieve. This procedure could also be applied to other sieve fractions being agreed on in the aluminum industry as specified in 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
