ActiveClassification system and test methods for nonmetallic gasket materials - Part 4: Standard test method for sealability of gasket materials
非金属垫片材料分类体系及试验方法 第4部分:垫片材料密封性试验方法
Application Summary AI generated
This standard specifies a test method for measuring the sealability of nonmetallic gasket materials under controlled compressive load and internal pressure conditions. It is applied in the mining and industrial sectors to evaluate how effectively gasket materials prevent fluid leakage in flanged joints, piping systems, and equipment seals. The test results guide material selection and quality control for gaskets used in high-pressure or critical sealing applications.
