(Practice)Standard Practice for Carbon Black—Sampling Packaged Shipments
Standard Practice for Carbon Black—Sampling Packaged Shipments
SIGNIFICANCE AND USE
This practice is for use in obtaining representative samples of carbon black from the packages in the shipment. These samples are used to determine the average quality or variability of the shipment.
SCOPE
1.1 This practice covers the sampling of packaged carbon blacks for shipment in bags, cartons, flexible immediate bulk containers (FIBC), or other non-bulk packages.
Note 1—The tests to be made on the samples obtained by this practice shall be determined by the producer and the consumer. The specific details of each test method are described in appropriate ASTM 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.
