1.1 这些试验方法包括测定双（三乙氧基甲硅烷基丙基）氨基硅烷或硅烷和炭黑混合物的硫含量。包括以下测试方法: 试验方法A:在氧气瓶中的燃烧及随后的试验 硫酸盐的滴定 试验方法B:红外线高温燃烧 吸收检测 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====== 3.1 硫含量可用于表征硅烷或硅烷和炭黑的混合物。它主要取决于硫链的平均长度。

1.1 These test methods cover the determination of the sulfur content of silanes, or of admixtures of silane and carbon black, of the type bis-(triethoxysilylpropyl)sulfane. The following test methods are included: Test Method A: Combustion in an Oxygen Flask and Subsequent Titration of Sulfate Test Method B: High-Temperature Combustion with Infrared Absorption Detection 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 ====== 3.1 The sulfur content can be used to characterize a silane or an admixture of silane and carbon black. It depends mainly on the average length of the sulfur chain.
