1 Subject content and applicable scope This standard specifies the method for determining the Mooney viscosity of raw rubber or rubber compounds with a rubber Mooney viscometer. This standard is applicable to the determination of Mooney viscosity of various raw rubber or unvulcanized rubber compounds. 2 Normative references GB/T 2941 Rubber - Standard temperatures, humidities and times for the conditioning environmental and testing of test pieces GB 6038 Rubber test mixes - Preparation, mixing and vulcanization - Equipment and procedures ZB N72 024 Technical specifications for rubber Mooney viscometer 3 Test principle This standard measures the torque required to rotate the rotor in a rubber-filled die cavity under specified test conditions and uses the Mooney viscosity as a unit of measuring for this torque. 4 Test instruments 4.1 The Mooney viscometer used in this standard shall comply with those specified in ZB N72 024.
