1. Scope 1.1 This test method provides a means to determine operating temperature limits for polytetrafluoroethylene (PTFE) based sheet or sheet-like gaskets to assist in avoiding catastrophic failure or blowout. 1.2 This test method focuses on flanged joints common in the chemical process industry for moderate temperature ASME B16.5 Class 150 and Class 300 services.
This is a test of the performance of the gasket material under heat and pressure.
