AbolishedRubber，vulcanized--Determination of low-temperature characteristics--Temperature-retraction procedure(TR test)
硫化橡胶 低温性能的测定 温度回缩法(TR试验)
Application Summary AI generated
This standard specifies the temperature-retraction (TR) test method for measuring the low-temperature characteristics of vulcanized rubber. It is applied in the rubber industry to evaluate the ability of rubber products, such as seals, hoses, and gaskets, to recover from elongation at low temperatures. The test is critical for quality control and material selection in automotive, aerospace, and industrial applications where rubber components must maintain flexibility and sealing performance in cold environments.
