ASTM WK61856

    New Test Method for Hot Blowout and Thermal Cycling Performance for Polytetrafluoroethylene (PTFE) Sheet or Sheet-Like Gaskets

    (What is a Work Item?)

    Developed by Subcommittee: F03.20 | Committee F03 | Contact Staff Manager


    1. Scope

    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.


    Flange connection


    This is a test of the performance of the gasket material under heat and pressure.

    The title and scope are in draft form and are under development within this ASTM Committee.
