1、Designation: D1513 05 (Reapproved 2012)Standard Test Method forCarbon Black, PelletedPour Density1This standard is issued under the fixed designation D1513; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.
2、 A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method covers the determination of the po

Summary of Test Method3.1 Pour density is determined by measuring the mass ofcarbon black in a known volume.4. Significance and Use4.1 Pour density is a function of the degree o

Pour density of carbon blackis useful for estimating the weight-to-volume relationship forcertain applications, such as automatic batch loading systems,and for estimating weights of bulk ship
