Discussion
In a rubber sample with a Mooney viscosity of 60 ML(1+4) 100 °C, the number 4 signifies
Answer: C
The 4 is the time in minutes after starting the motor when the measurement is taken.
In the notation ML(1+4) 100 °C, M is Mooney, L the large rotor, 1 the preheating time in minutes, 4 the running time in minutes after the rotor is started, at which the reading is taken, and 100 °C the test temperature. 60 is the Mooney viscosity in Mooney units.
So 4 is not the preheating time (that is the 1), not the number of samples, and not a shear rate: the Mooney viscometer runs its rotor at a fixed speed (2 rpm) that the notation does not state.
