1、Designation:D500411(Reapproved 2017)Standard Test Method forReal Density of Calcined Petroleum Coke by XyleneDisplacement1This standard is issued under the fixed designation D5004;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the y

2、ear of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the realdensity(RD)of calcined petroleum coke.Real density,bydefinition

3、,is obtained when the particle size of the testspecimen is smaller than 75 m(No.200 sieve).1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns,if any,associa

4、ted with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For specific warning statements,see Sections 10 and 11.1.1.4 This international standard w
