Standard Test Methods for Rubber From Synthetic Sources—Volatile Matter 合成橡胶挥发性物质的标准试验方法
发布日期: 2021-12-01
1.1 这些试验方法包括热轧法、两种烘箱法和压榨法,用于测定合成橡胶中的水分和其他挥发物含量。 1.2 尤其是当橡胶太粘而无法在热轧机上令人满意地处理时,应使用任何一种烘箱方法。 1.3 对于太易碎而无法在实验室磨机上令人满意地保留的橡胶,应使用压制法。 1.4 以国际单位制表示的数值应视为标准。括号中的值仅供参考。 1.5 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。 1.6 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====== 3.1 这些测试方法主要用于仲裁目的,但也可用于橡胶生产的质量控制。 3.2 挥发物的数量会影响复合橡胶的加工和固化特性。
1.1 These test methods cover a hot mill method, two oven methods, and a press method for the determination of moisture and other volatile matter content in synthetic rubber. 1.2 Either oven method shall be used especially when the rubber is too tacky to be handled satisfactorily on a hot mill. 1.3 The press method shall be used for rubbers that are too crumbly to be retained satisfactorily on a laboratory mill. 1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 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 ====== 3.1 These test methods are mainly intended for referee purposes but can also be used for quality control of rubber production. 3.2 The amount of volatiles can affect processing and cure characteristics of compounded rubber.
