WebNIST Technical Series Publications Web4.1.1 Part A—Viscosity: This test method describes the measurement of the Mooney viscosity. The Mooney viscosity is measured by a metal disk embedded in a rubber specimen contained in a rigid cylindrical cavity maintained at a specified pressure and temperature. The disk is slowly and continuously rotated in one direction for a specified …
