ISO 289-2
Rubber, unvulcanized -- Determinations using a shearing-disc viscometer -- Part 2: Determination of pre-vulcanization characteristics


ISO 289-2 specifies the test method for determining Mooney viscosity of raw natural and synthetic rubber. Using a standardized Mooney viscometer, this test measures the flow resistance of elastomeric materials by recording the torque required to rotate an immersed rotor within a heated sample. Essential for raw material quality control and production consistency, the method enables manufacturers to assess rubber workability, optimize mixing parameters, and ensure uniform properties in final compounds.
