【国外标准】 Standard Test Methods for Rubber Compounding Materials—Determination of Volatile Material

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.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:  SectionSulfur 7 – 13p-Phenylenediamine antidegradants 14 – 211.3 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.
