Rubber, unvulcanized. Determinations using a shearing-disc viscometer. Determination of the Mooney stress-relaxation rate | Status: Superseded, Withdrawn

1 Scope This part of ISO 289 specifies a method of use of a shearing-disc viscometer for measuring the Mooney stress-relaxation rate (MSR) of uncompounded or compounded unvulcanized rubbers, characterizing the elastic response of those materials next to the viscous response as measured by the Mooney viscosity.
