1.1 这些试验方法包括根据在70°C下加热时的质量损失来测定各种橡胶化学品中挥发性物质的损失。 1.2 这些测定挥发性物质的试验方法包括以下材料: 部分 硫黄 7 – 13 p -苯二胺抗降解剂 14 – 21 1.3 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。 1.4 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。 1.5 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====== 5.1 这些试验方法适用于测定橡胶复合材料中的挥发性物质。测试方法可用于质量控制、产品验收或研发。分类 D4676号 规定挥发性物质百分比是橡胶防降解剂的一个重要特征。

1.1 These test methods cover the determination of the loss of volatile materials in various rubber chemicals based on the mass loss upon heating at 70°C. 1.2 These test methods for the determination of volatile matter include the following materials: Section Sulfur 7 – 13 p -Phenylenediamine antidegradants 14 – 21 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. 1.5 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 These test methods are suitable for the determination of volatile material in rubber compounding materials. The test methods may be used for quality control, product acceptance, or research and development. Classification D4676 prescribes percent volatile material as an important characteristic of rubber antidegradants.
