1.1 本规程涵盖了在三室料斗轨道车和隔间散装料斗拖车中散装运输炭黑的采样和数据报告程序。 注1: 对通过本规程获得的样品进行的测试、取样数量、取样地点以及报告的统计值（如有）应由买方和制造商之间的协议确定。本实践为制定此类协议或在不存在正式协议的情况下使用提供了指导。用于测试炭黑的适当ASTM测试方法中描述了每个程序的具体细节。 注2: 一些购买者或制造商可能会将柔性中间散装集装箱（FIBC）视为散装货物。参见练习 D1799 有关此程序包的采样和报告指南。 1.2 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 散装炭黑的采样至关重要，因为不同实验室采集的样本的位置和数量可能会对获得的测试值的一致性产生重大影响。本规程用于获取每个隔间或整个漏斗车或漏斗车中的代表性炭黑样品。这些样品可用于确定货物的平均质量或均匀性，或两者兼而有之。

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. ====== 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.
