Rubber, unvulcanized — Determinations using a shearing-disc viscometer — Part 4: Determination of the Mooney stress-relaxation rate
橡胶 未硫化 - 使用剪切盘式粘度计测定 - 第4部分:门尼应力松弛率的测定
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.
