ActiveClassification system and test methods for nonmetallic gasket materials—Part 5: Standard test method for creep relaxation of gasket materials
非金属垫片材料分类体系及试验方法 第5部分：垫片材料蠕变松弛率试验方法
Application Summary AI generated
This standard specifies the test method for measuring the creep relaxation rate of nonmetallic gasket materials. It is applied in the design and quality control of static sealing joints in fluid systems, such as flanged connections in pipelines, pumps, and valves, where maintaining bolt load over time is critical to prevent leakage.
