Mooney rubber Viscometer testing machine
It is an instrument used for measuring the mooney viscosity of a substance (mainly elastomers and rubbers). It contains a rotating spindle and heated dies, the substance encloses and overflow the spindle and the mooney viscosity is calculated from the torque on the spindle.

Test Results
Measure of Mooney viscosity (Large rotor):
MI -- initial Mooney viscosity.
ML – The minimum Mooney value in the last 30 seconds before the motor stopped.
Mx-t - Mooney value relating to time t.
x-the time of preheat, t-Mooney test time
Stress Relaxation
MRe - Mooney value at the end of stress relaxation.
TRx - time needed for x% torque stress relaxation.
Xy% - % of Viscosity decay after motor stopped y sec.
The value of exponent a, the constant k, the correlation coefficient r, and the area A .
