The appropriate standards associated with this test are IS0 289, ASTM .
ISO 289 Parts 1 and 2 also describes the determination of Mooney viscosity and pre-vulcanization characteristics. In addition to a few insignificant differences there are major technical differences between ISO 289 and this test method in that ISO 289 does not provide for sample preparation on a mill, while this test method allows milling .ISO 289-1:2015 specifies a method using a shearing-disc viscometer for measuring the Mooney viscosity of uncompounded or compounded rubbers.

Overview The MooneyCheck - Drive is a Mooney Viscometer, which permits to measure the Mooney viscosity, Pre-curing (scorch) and Stress Relaxation Characteristics of uncompounded or compounded rubbers In conformity with ISO 289-1, . It is interesting that the Mooney viscosity for one of the `bad' lots was very close to the Mooney viscosity for the `good' lot (ML1+4 of 93 vs 94). Table 11 gives a description of these three lots. Fig. 31 shows very good separation of the `good' vs the `bad' lots of natural rubber when comparing the uncured tan δ at high strain test conditions. Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity. NIR reflectance spectra were obtained for a total of 100 samples whose Mooney viscosity (VM in the range 68–95 units) have been determined by the standard reference .

Using functional analysis, Mooney derived the following equation to describe the relative viscosity/concentration behavior of rigid, spherical particles: T/, =exp[2.54>/(I-aM4>)) (1) where T/, is the relative viscosity, 4> is the volume fraction of the solids, and aM is
Traditional data-driven empirical models for online prediction of the Mooney viscosity have not utilized the information hidden in lots of unlabeled data (e.g., process input variables during each mixing batch). A simple semi-supervised nonlinear soft sensor method for the Mooney viscosity prediction is developed.The Mooney viscosity of the sample set was measured by the standard method and the values were in the range 65–95 units. The samples were divided in two subsets, one for calibration, containing 70 samples, and the other for external validation, containing the remaining 30 samples. The Mooney viscosity average values and their standard .Mooney Viscosity. The Mooney Viscosity test is the most popular test method for characterizing polymers and uncured rubber materials. As defined by international standards, the sample material is preheated for a defined period in a closed die cavity, then sheared by the embedded rotor at a constant rate.

Mooney viscometers are mainly used to test characteristics of raw materials before mixing - to verify that they meet required standards for the formulation in which they are to be used. To perform a Mooney Viscosity Test, the die cavity temperature is set and allowed to stabilize. Then, a specified volume of the sample material is loadedMooney viscometer The sample cavity of the Mooney vis-cometer is shown in Fig. 1. The rotor is embedded in a sample and the torque required to move the rotor at 2 rpm is measured. A typical Mooney viscosity measurement is the ML1+42. This test uses a 1 minute preheat with the motor off and then 4 minutes with the motor on at 2 rpm.PREFACE Thefactorsdiscussedinthispaperdonotbyanymeanscoverall thatmightbewrittenonthecareandoperationofMooneyviscom- eters .
