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, health, and environmental 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.

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.

5.2 Results from this test method are used in determining coke specifications, classification purposes, and for quality control.
