ActiveRubber, vulcanized—Determination of low-temperature characteristics—Temperature-retraction procedure (TR test)
硫化橡胶 低温性能的测定 温度回缩程序（TR 试验）
Application Summary AI generated
This standard specifies the temperature-retraction (TR) test method for determining the low-temperature characteristics of vulcanized rubber. It is applied in the rubber and plastic industry to evaluate how stretched rubber samples retract when warmed from a low temperature, providing data on crystallization and glass transition behavior. The test is used for quality control and material selection in products like seals, hoses, and tires that must maintain flexibility in cold environments.
