ASTM D1508-02e1

Standard Test Method for Carbon Black, Pelleted Fines and Attrition

SCOPE
1.1 This test method covers the determination of the fines and attrition of pelleted carbon black.
1.2 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.
