1.1 This test method details a procedure for performing particle size distribution analysis by dry sieve testing on green petroleum coke with a topsize of no more than 75 mm and calcined petroleum coke with a topsize of no more than 25 mm. Size fractions go down to and include 4.75 mm for green petroleum coke and 75 μm for calcined petroleum coke.

Note 1: To convert units, see Table 1 on nominal dimensions in Specification E11. For example, 75 mm is approximately equivalent to a nominal sieve opening of 3 in. and 25 mm to a nominal sieve opening of 1 in. Likewise, 4.75 mm can be converted to approximately 0.187 in. and 75 microns to 0.0029 in.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1 The sieve size is reported as U.S.A. standard test series in any units listed in Table 1 on nominal dimensions of Specification E11, or their commercial size equivalents.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Significance and Use

5.1 The test method concerns the sieving of coke into designated size fractions for the purpose of characterizing the material as to its particle size distribution. It requires the use of standard sieves, standard sampling methods, standard sample preparation methods, and a minimum initial sample mass based on lot topsize. Suggestions are given for industry typical sieve stacks for both green and calcined petroleum coke.

5.2 Particle size distribution is significant in that many physical characteristics of a coke are related to such a distribution including bulk density and surface area. Nuisance characteristics, such as excessive fines in a lot, can also be controlled.

5.3 Results from this test method are useful in determining whether a coke lot meets purchase specifications, for classification purposes, and for quality control. The results of this test method can also be used to predict the performance of a particular lot of coke in a process.
