1.1 This test method is used to rheologically determine the degree of silanization in a silica filled compound. Silanization is the chemical reaction related to covering the silica surface with organosilanes for a better incorporation of silica into rubber. Bifunctional silanes can provide coupling between silica and rubber for enhanced rubber reinforcement.
1.2 Units—The values stated in SI units are to be regarded as the 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.
