This standard specifies a method for determining the Mooney stress relaxation rate of unvulcanized rubber using a shear disc Viscometer. Mooney stress relaxation rate is an important parameter characterizing the molecular chain structure and processing performance of unvulcanized rubber, and can be used to evaluate the rheological performance and processing Stability of rubber. This standard describes in detail the requirements of the test instrument, the setting of the test conditions, the test procedure and the calculation method of the results to ensure the repeatability and conformity of the data.
