Significance and Use
These test methods are mainly intended for referee purposes but may be used for quality control of synthetic rubber production. They may also be used in research and development work and for comparison of different rubber samples in a standard formula.
These test methods may also be used to obtain values for customer acceptance of rubber.
1.1 These 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.
1.2 These test methods are also applicable to certain types of solution SBR and solution SBR oil masterbatches that are used in applications requiring vulcanization.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This 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.
