GB/T 1685-2008
ActiveRubber，vulcanized or thermoplastic - Determination of stress relaxation in compression at ambient and at elevated temperatures
硫化橡胶或热塑性橡胶 在常温和高温下压缩应力松弛的测定
Application Summary AI generated
This standard specifies a test method for measuring the decrease in compressive force over time in vulcanized or thermoplastic rubber under constant strain at room temperature and elevated temperatures. It is primarily applied in the rubber industry for quality control and material selection of sealing components, such as gaskets, O-rings, and pads, where long-term sealing performance under sustained compression is critical. The test helps predict the service life and reliability of rubber parts in applications like automotive engines, industrial machinery, and fluid handling systems.
