Standard Test Method for Carbon Black, Pelleted—Mass Strength 炭黑颗粒质量强度的标准试验方法
发布日期: 2023-05-01
1.1 本试验方法涵盖了颗粒炭黑质量强度的测定。它的设计目的是确定填充一个圆柱形的颗粒状炭黑柱所需的力。该测试的结果被认为与炭黑在散装处理系统中流动的能力有关。 1.2 以国际单位制表示的数值应视为标准。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)。本标准的使用者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》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 质量强度指示了散装处理中的流动性。它受到颗粒特性的影响,如硬度、尺寸、形状,尤其是细粒含量。由于其他变量的影响,用户和生产商必须确定可接受的质量强度水平。
1.1 This test method covers the determination of the mass strength of pelleted carbon black. It is designed to determine the force required to pack a cylindrical column of pelleted carbon black. The results of this test are believed to relate to the ability of the carbon black to flow in bulk handling systems. 1.2 The values stated in SI units are to be regarded as the 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 ====== 4.1 Mass strength gives an indication of the flowability in bulk handling. It is affected by pellet properties such as hardness, size, shape, and especially fines content. Due to the influence of other variables, the user and the producer must determine an acceptable mass strength level.
