ASTM D1513-05e2

Standard Test Method for Carbon Black, Pelleted—Pour Density

SIGNIFICANCE AND USE
Pour density is a function of the degree of compaction during pelletization. It is strongly influenced by and inversely proportional to structure (OAN). Pour density of carbon black is useful for estimating the weight-to-volume relationship for certain applications, such as automatic batch loading systems, and for estimating weights of bulk shipments.
SCOPE
1.1 This test method covers the determination of the pour density of pelleted carbon blacks.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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 and health practices and determine the applicability of regulatory limitations prior to use.
