Rubber, unvulcanized — Determinations using a shearing-disc viscometer — Part 4: Determination of the Mooney stress-relaxation rate

ISO/TS 289-4 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. The intended use of this document is on quality control measurements.
