1.1 本试验方法涵盖硅烷或硅烷和炭黑混合物的特性（见 10.4 )，通过高效液相色谱法测定双-（三乙氧基甲硅烷基丙基）砜型。 1.2 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。 1.3 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。 1.4 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====== 5.1 平均硫链长是决定硅烷在橡胶混合物中行为的一个重要参数。

1.1 This test method covers the characterization of silanes, or of admixtures of silane and carbon black (see 10.4 ), of the type bis-(triethoxysilylpropyl)sulfane by high performance liquid chromatography. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 ====== 5.1 The average sulfur chain length is an important parameter in determining the behavior of the silane in a rubber mixture.
