1、Designation:D570922Standard Test Method forSieve Analysis of Petroleum Coke1This standard is issued under the fixed designation D5709;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses i
2、ndicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method details a procedure for performingparticle size distribution analysis by dry sieve testing on greenpetroleum coke with a topsize of no more than
3、 75 mm andcalcined petroleum coke with a topsize of no more than 25 mm.Size fractions go down to and include 4.75 mm for greenpetroleum coke and 75 m for calcined petroleum coke.NOTE1To convert units,see Table 1 on nominal dimensions inSpecification E11.For example,75 mm is approximately equivalent
4、to anominal sieve opening of 3 in.and 25 mm to a nominal sieve opening of1 in.Likewise,4.75 mm can be converted to approximately 0.187 in.and75 microns to 0.0029 in.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.2.1 The si
