Standard Test Method for Rubber Properties—Measurement of Cure and After-Cure Dynamic Properties Using a Rotorless Shear Rheometer
1.1 This test method covers the use of a rotorless oscillating shear rheometer for measuring after cure dynamic properties at predetermined temperature(s) below the cure temperature.
1.2 Specified cure conditions that approximate a “static cure” also are covered to minimize effects on cured rubber compound dynamic properties. This test method is not intended to replace Test Method D5289.
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 Warning—Compounds based on silicone or fluoroelastomers may have high levels of thermal contraction or poor adhesion to the dies when cooled after the cure portion of this test method, causing slippage during strain sweeps. If this occurs, the results will not be reliable.
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.
