ActiveRubber, vulcanized or thermoplastic—Determination of stress relaxation in compression—Part 2: Testing with temperature cycling
硫化橡胶或热塑性橡胶 压缩应力松弛的测定 第2部分：循环温度下试验
Application Summary AI generated
This standard specifies a method for measuring the stress relaxation of vulcanized or thermoplastic rubber under compression while undergoing cyclic temperature changes. It is applied in quality control and material selection for rubber seals, gaskets, and O-rings used in automotive engines, aerospace components, and industrial machinery that experience fluctuating thermal environments. The test evaluates long-term sealing performance and durability by simulating real-world temperature cycling conditions.
