1.1 This test method covers the determination of bulk density of a representative 2-kg sample of calcined petroleum coke, after vibration to increase compaction, using a semi-automatic apparatus. 1.2 The procedure is applied, but not limited, to particles passing through a 4.75-mm opening sieve and retained on a 1.18-mm opening sieve. Further, the procedure is applied, but not limited, to a specific test sample having particles passing through a 0.8
