This test method is useful for determining the variability in material and the influence of parameters affecting the stress-strain properties of rubber vulcanizates, for example, temperature, relative humidity, preconditioning of rubber, and so forth. This test method is particularly useful for the evaluation of compounding materials used for reference purposes.

1.1 This test method covers determination of the elongation of soft vulcanized rubber compounds under a specified stress.

1.2 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.
