1.1 This test method covers a laboratory vibration mill method for the determination of the grain stability of calcined coke for the manufacture of carbon products used in the smelting of aluminum. Calcined coke with poor mechanical strength may become degraded during mixing. Poor grain stability will affect the grain size and may result in poor quality of baked blocks.
1.2 The values stated in acceptable metric units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use.
