适用范围：1.1 This standard describes a procedure for the determination of bulk density of a representative 2 kg sample of calcined petroleum coke, after vibra-tion to increase compaction.1.2 The procedure is limited to particles passing through a 6.68 mm opening sieve ( equivalent to a 3-mesh Tyler Standard Series ) and retained on a 0.21 mm opening, No. 70, sieve ( equivalent to a 65-mesh Tyler Standard Series ). Further, the pro-cedure is limited to a specilic test sample having particles retained between screens having openings that differ by a factor of less than 2∫2 and pre-ferably less than 2.1.3 This procedure does not specify the method by which the 2 kg sample is obtained from a large lot of calcined coke. The procedure for obtaining the sample could include multiple sampling, breaking up particles with diameters greater than about 20 mm, and riffling.1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems asso-ciated with its use. It is the responsibility of who-so-ever uses this standard to consult and establish appro-priate safety and health practices and determine the applicability of regulatory limitations prior to use.
