1.1 本规程涵盖了用于物理试验、化学分析和总水分测定的焦炭样品的收集和还原程序。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.2.1 以国际单位制[或英寸磅单位]为单位的数值应通过以国际单位制[或英寸磅单位]为单位的测量或通过适当的转换获得，使用中给出的转换和舍入规则 IEEE/ASTM SI 10 ，以国际单位[或其他单位]进行测量。当实际中未使用英寸-磅单位时，数值以国际单位制表示。 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 本规程可用于提供收集焦炭的代表性样品。由于焦炭的可变性和取样设备的多样性，从系统规范和设备采购到设备验收测试以及实际采集最终样品，在取样的所有阶段都必须谨慎。 3.2 本规程还提供了总样本或分割样本中的焦炭分析样本。分析样品可用于确定所代表焦炭的价值、其满足规范的能力以及其他目的。

1.1 This practice covers procedures for the collection and reduction of samples of coke to be used for physical tests, chemical analyses, and the determination of total moisture. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.2.1 Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI 10 , of measurements made in SI units [or other units]. Values are stated in SI units when inch-pound units are not used in practice. 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 This practice may be used to provide a representative sample of the coke from which it is collected. Due to the variability of coke and the wide variety of sampling equipment, caution must be exercised in all stages of sampling, from system specifications and equipment procurement to equipment acceptance testing and actually taking the final sample. 3.2 This practice also provides an analysis sample of coke from the gross or divided sample. The analysis samples can be used to determine the value of the coke represented, its ability to meet specifications, as well as for other purposes.
