ActiveRubber,vulcanized or thermoplastic—Determination of compression set—Part 1: At ambient or elevated temperatures
硫化橡胶或热塑性橡胶 压缩永久变形的测定 第1部分：在常温及高温条件下
Application Summary AI generated
This standard specifies the method for measuring the compression set of vulcanized or thermoplastic rubber under constant deflection at ambient or elevated temperatures. It is applied in the rubber and plastics industry to evaluate the elastic recovery and sealing performance of materials used in gaskets, O-rings, and other rubber components subjected to prolonged compressive stress. The test is critical for quality control and material selection in automotive, aerospace, and industrial sealing applications.
