1.1 This test method covers the determination of the apparent density of core samples from manufactured articles of anode and cathode carbon used by the aluminum industry in the production of aluminum. 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. ====== Significance And Use ====== 4.1 Apparent density as determined by this test method is a basic material property of importance in manufacturing and application of anode and cathode carbon. 4.2 This test method can be used for quality and process control, material characterization and description, and other purposes.
