ASTM D5502-00(2005)
(Test Method)Standard Test Method for Apparent Density by Physical Measurements of Manufactured Anode and Cathode Carbon Used by the Aluminum Industry
Standard Test Method for Apparent Density by Physical Measurements of Manufactured Anode and Cathode Carbon Used by the Aluminum Industry
SIGNIFICANCE AND USE
Apparent density as determined by this test method is a basic material property of importance in manufacturing and application of anode and cathode carbon.
This test method can be used for quality and process control, material characterization and description, and other purposes.
SCOPE
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 the standard. The values given in parentheses are for information only.
1.3This 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.
