Standard Practice for Carbon Black—Sampling Bulk Shipments
SCOPE
1.1 This practice outlines procedures for the sampling and data reporting of bulk shipments of carbon black in three-compartment hopper rail cars, but the same principles can apply to sampling compartmented bulk highway trailers as well.
Note 1—The tests to be made on the samples obtained by this practice shall be determined by the purchaser and the manufacturer. The specific details of each procedure are described in appropriate ASTM test methods used for testing carbon black.
1.2 The values stated in SI units are to be regarded as the standard. The values 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.
