ASTM D4292-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D4292 − 17 D4292 − 23
Standard Test Method for
Determination of Vibrated Bulk Density of Calcined
1
Petroleum Coke
This standard is issued under the fixed designation D4292; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
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 0.265 in. USA Series) and
retained on a 0.21 mm opening sieve (equivalent to a 70 mesh USA 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 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.

3. Terminology
3.1 Definitions:
3.1.1 For definitions of terms used in this test method, refer to Terminology D4175.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 as-calcined particles, n—of coke, those particles that have not been subject to laboratory crushing.
3.2.2 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.
3.2.3 gross sample, n—the original, uncrushed, representative portion taken from a shipment or lot of coke.
3.2.4 laboratory crushed particles, n—of coke, those particles of petroleum coke that have been crushed in the laboratory.
4. Summary of Test Method
4.1 After appropriate crushing of the calcined coke, using both the jaw crusher and roll crusher, the test volume of 100 g is
measured after vibration and the bulk density is calculated.
5. Significance and Use
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. (Warning—Vibrated bulk density for a sample of calcined petroleum coke is strongly de
