ISO 289-1:2015 specifies a method using a shearing-disc viscometer for measuring the Mooney viscosity of uncompounded or compounded rubbers. General information. Status : Published. Publication date : 2015-09. Stage: International Standard confirmed Edition : 4. Number of pages : 17. Technical Committee : 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.
