ASTM D4292 Test Method for Determination of Vibrated Bulk Density of Calcined Petroleum Coke
1. Scope
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.
1.2 The procedure is limited to particles passing through a 6.68-mm opening sieve (equivalent to a 3-mesh Tyler Standard Series) and retained on a 0.21-mm opening sieve (equivalent to a 65-mesh Tyler Standard Series). Further, the procedure is limited to a specific test sample having particles retained between screens having openings that differ by a factor of less than 2√2 and preferably less than 2.
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.

3. Terminology
3.1 Definitions ofTerms Specific to This Standard:
3.1.1 as-calcined particles, n - of coke, those particles that have not been subject to laboratory crushing.
3.1.2 bulk density, n - of coke, the ratio of the mass of a collection of particles of a specified particle size range to the volume occupied.
3.1.3 gross sample, n - the original, uncrushed, representative portion taken from a shipment or lot of coke.
3.1.4 laboratory crushed particles, n - of coke, those particles of petroleum coke that have been crushed in the laboratory.
