ASTM D2414-06

Standard Test Method for Carbon Black-Oil Absorption Number (OAN)

SCOPE
1.1 This test method covers the determination of the oil absorption number 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.
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.
