1.1These test methods cover the standard materials, test formulas, mixing procedures, and test methods for the evaluation of emulsion polybutadiene (EBR) and styrene-butadiene rubbers (SBR) including the emulsion polybutadiene oil masterbatch rubbers, SBR oil masterbatches, and partially crosslinked and high Mooney rubbers.

1.2These test methods are also applicable to certain types of solution SBR and solution SBR oil masterbatches that are used in applications requiring vulcanization.

1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4This 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 and health practices and determine the applicability of regulatory limitations prior to use.
