ASTM D5605-94R21 - Standard Practice for Styrene-Butadiene Rubber (SBR)—Establishing Raw Mooney Viscosity Target Values

1.1 This practice covers a means for producers and users of emulsion styrene-butadiene rubber (SBR) to establish common target values for the Mooney viscosity of these rubbers.

1.2 Mooney viscosity is a widely used measurement for rubber as defined in Test Methods D1646 where the procedure for its measurement is specified.

1.3 The Mooney viscosity target value is defined as the midpoint of a Mooney viscosity specification range established by a producer or user of rubber.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
