GB/T 1232.1-2016 is a fundamental standard in the rubber industry, specifying the method for determining the Mooney viscosity of unvulcanized rubber using a shearing disc-type Mooney viscometer. By measuring the torque required for a rotor to rotate within a sealed cavity filled with a rubber sample, a dimensionless Mooney value (ML 1+4) is obtained. This value is widely used for quality control of rubber compound processing properties (such as plasticity and uniformity) and for formulation comparisons.
