ASTM D1511-10

Standard Test Method for Carbon Black—Pellet Size Distribution

SIGNIFICANCE AND USE
The variation in the size of the pellets may relate to the level of dispersion and to the ease of handling. Due to the many other variables that influence dispersion and handling, the significance of pellet size must be determined by the user.
SCOPE
1.1 This test method covers the determination of the pellet size distribution of carbon black.
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.
