| Significance and Use | ||||
|
3.1?Sampling of bulk shipments of carbon blacks is of utmost importance since the location and number of samples taken by different laboratories can have a significant effect on the agreement of test values obtained. This practice is for use in obtaining representative samples of carbon black in each compartment or in the entire hopper car or hopper truck. These samples may be used to ascertain the average quality or the uniformity of a shipment, or both. |

| 1. Scope | ||||
|
1.1?This practice covers procedures for the sampling and data reporting of bulk shipments of carbon black in three-compartment hopper rail cars and compartmented bulk hopper trailers. Note 1:?The tests to be made on the samples obtained by this
practice, how many samples are taken, where they are taken, and
what statistical values (if any) to report shall be determined by
agreement between the purchaser and the manufacturer. This practice
gives guidance for use in developing such agreements or for use
when no formal agreement exists. The specific details of each
procedure are described in appropriate ASTM test methods used for
testing carbon black.
Note 2:?Some purchasers or manufacturers may consider Flexible
Intermediate Bulk Containers (FIBC) to be a bulk shipment. See
Practice D1799 for guidance
on sampling and reporting for this package.
1.2?The values stated in SI units are to be regarded as 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
