ε NOTE—Editorially updated 3.1.1 in January 2020.
1. Scope
1.1 The test method covers the determination of bulk density for a specific size fraction of calcined petroleum coke using an
automated pycnometer that compacts coke by applying transaxial pressure under a controlled force.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.4 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 bulk density, n—of coke, the ratio of the mass of a collection of particles of a specified size range to the volume occupied.
3.1.2 transaxial pressure, n—pressure applied across a horizontal axis.
4. Summary of Test Method
4.1 A representative sample of calcined petroleum coke is collected and then screened using Specification E11 sieves (8 mm,
4 mm, 2 mm, 1 mm, 0.5 mm, 0.25 mm) into fractions. Each specific size fraction is then weighed and the bulk volume is measured
using the pycnometer. This test method measures the bulk volume by controlling the consolidation force and measuring the
displacement of a plunger used to compact the bed of coke.
5. Significance and Use
5.1 The bulk density is an indicator of calcined petroleum coke porosity and packing capability which is an important coke
property for anode production in aluminum industry. This procedure will allow an automated measurement of specific sized
fractions ranging from 8 mm to 0.25 mm coke particles.
