Significance and Use
This test method is used to measure viscoelastic properties of raw rubber as well as unvulcanized rubber compounds. These viscoelastic properties may relate to factory processing behavior.
This test method may be used for quality control in rubber manufacturing processes and for research and development testing of raw rubber and rubber compounds. This test method may also be used for evaluating compound differences resulting from the use of different compounding materials.
1. Scope
1.1 This test method covers the use of a rotorless oscillating shear rheometer for the measurement of the flow properties of raw rubber and unvulcanized rubber compounds. These flow properties are related to factory processing.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
