For the past 15--20 years, a major research program aimed at solving the problem of leakage of gasketed flanged joints has been undertaken by the Pressure Vessel Research Council (PVRC). This program has resulted in greatly enhanced understanding of the leakage phenomena of a flanged joint and improvements of the ASME Code design procedures. The PVRC bolted flanged program has been organized into six areas: (1) implement PVRC gasket constants and test procedure development; (2) issue a flange design guidelines report considering items such as modeling, tightness, transients, relaxation, etc.; (3) flange rating parameters for standard flanges; (4) design parameters for ASME joints; (5) gasket testing for temperature behavior data and test method developments; and (6) flanged joint assembly and interaction effects. This paper presents an update of the recent developments in the area of gasket testing; specifically, testing on flexible graphite gaskets, elastomeric sheet gaskets, and fugitive emissions gasket characteristics with various types of fluids are described.
