1.1These test methods explain the use of the shearing disk viscometer to obtain an indication of the processability of non-pigmented emulsion styrene-butadiene rubbers (SBR). The test methods described should not be used to compare processability characteristics of polymers that produce a test curve significantly different from that shown in Fig. 1.

1.2The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4This 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.
