1.1 该试验方法涵盖了一种通过使用反射模式下的光学显微镜量化新切割样品的表面粗糙度来测量橡胶基体中填料的宏观分散度的程序。 1.2 该方法提供了一种测量增强填料如二氧化硅和炭黑以及惰性填料如白垩、粘土和其他固体的混合质量的程序。 1.3 该方法包括填充的未固化橡胶化合物以及填充的固化橡胶化合物的样品制备程序。 1.4 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.5 本标准并不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。 1.6 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====== 5.1 将填料掺入橡胶基体的特征在于它们的宏观分散性作为混合质量的指标。该测试方法提供了增强填料（如二氧化硅和炭黑）以及惰性填料的宏观分散度的测量。根据其聚合物性质，不同类型的橡胶可以表现出不同程度的填料掺入接受度，如其宏观分散性所示。 5.2 炭黑和二氧化硅在橡胶化合物中的宏观分散度可以通过不同的方法测量。炭黑提供了直接的物理增强；二氧化硅需要硅烷偶联剂来引发增强，因此需要不同的混合技术。二氧化硅也是一种非导体，因此用电学方法测量色散是不可行的。该测试方法特别适用于二氧化硅技术中宏观分散体的表征。 5.3 该测试方法还可以测量彩色橡胶的混合质量。它使用可变曝光，以便能够拍摄各种颜色的图像。 5.4 本试验方法用于橡胶中填料可加工性的研究和开发以及质量控制，可用于生产过程的评估或裁判目的。

1.1 This test method covers a procedure to measure the macro-dispersion of fillers in a rubber matrix by quantifying the surface roughness of a freshly cut specimen using an optical microscope in reflection mode. 1.2 The method provides a procedure to measure the quality of mixing of reinforcing fillers such as silica and carbon black, as well as inert fillers such as chalk, clay and other solids. 1.3 The method includes a sample preparation procedure for filled uncured rubber compounds as well as filled cured rubber compounds. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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 ====== 5.1 The incorporation of fillers into the rubber matrix is characterized by their macro-dispersion as an indicator of the quality of mixing. This test method provides a measure of the macro-dispersion of reinforcing fillers, like silica and carbon black, as well as of inert fillers. Based on their polymer nature, different types of rubbers can show a different degree of acceptance for the incorporation of fillers, as indicated by their macro-dispersion. 5.2 Macro-dispersion of carbon black and silica in rubber compounds may be measured by different methods. Carbon black provides a direct physical reinforcement; silica requires a silane coupling agent in order to initiate reinforcement, and therefore, a different technology of mixing. Silica is also a non-conductor, making electrical methods of dispersion measurement impracticable. This test method is specifically appropriate for the characterization of the macro-dispersion in silica technology. 5.3 This test method also can measure the mixing quality of colored rubbers. It uses variable exposure in order to be able to image a wide range of colors. 5.4 This test method is intended for use in research and development as well as in quality control of filler processability in rubber and may be used for both the evaluation of production processes or referee purposes.
