• Phạm vi áp dụng / Scope of standard: 1.1 This test method covers a laboratory vibration mill method for the determination of the grain stability of calcined petroleum coke for the manufacture of carbon products used in the smelting of aluminum. Calcined petroleum 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 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 and health practices and determine the applicability of regulatory limitations prior to use.
