The three PVRC project reports presented in this Bulletin are concerned with elevated temperature sheet gasket performance in steam media.The steam media was an important factor for each of the Projects, thus setting them apart from previous PVRC gasket test programs.In addition, these projects were created as follow-up efforts to address questions arising out of MTIs Project No. 47 and subsequent PVRC and private gasket test projects.It is the purpose of this extended Foreword to provide the reader with additional background, references, and insights concerning the work and tests reported by this Bulletin.A major aspect of the MTI and PVRC work was the characterization of the long-term performance and thermal degradation of fiber reinforced elastomer bounds gaskets and flexible graphite sheet gaskets.However, those test programs were conducted with still air in the case of ATRS relaxation tests and with nitrogen or helium as contained media with still air surrounding the gasket outside diameter in the case of HOTT tests. Subsequent PVRC Projects developed the AHOT test as an extension of the HOTT test that considers longer aging times, and the ARLA test as a more sophisticated extension of the ATRS relaxation test.Again, these tests were conducted with hot gases and the question remained: What about long-term gasket performance in a steam media? To address this question the PVRC Committee on Bolted Flanged Connections initiated Projects 92-24, 26, and 27 to investigate the effect of steam media.
