Application Summary AI generated

This standard specifies a test method for measuring the stress relaxation behavior of gaskets used in pipe flanges under compressive load and elevated temperature. It is applied in the design, quality control, and material selection of gaskets for bolted flange connections in industrial piping systems, such as those in petrochemical, power generation, and process plants. The test helps ensure long-term sealing integrity by evaluating how much clamping force a gasket retains over time.
