Rubber, vulcanized — Determination of low-temperature retraction (TR test)

ISO 2921:2011 specifies a method for the determination of the temperature-retraction characteristics of stretched vulcanized rubber.

It does not cover thermoplastic rubbers, as many thermoplastic elastomers have a yield point in the range of 5 % to 20 % elongation. This fact might affect the result when carrying out temperature-retraction tests on thermoplastic rubbers, and the results obtained from such tests should be analysed with caution.
