Rubber, vulcanized — Determination of low-temperature retraction (TR test)
Additional Comments: ENGLISH
Published By:International Organization for Standardization (ISO)
This International Standard specifies a method for the determination of the temperature-retraction characteristics of stretched vulcanized rubber.
This International Standard 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 TR tests on thermoplastic rubbers, and the results obtained from such tests should be analysed with caution.
