ASTM D5605 : 94(2016)

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

Standard Details

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.
