Pressure ratings are maximum allowable non-shock working pressures (psig or bar gauge)
Intermediate temperatures may be interpolated linearly between tabulated values
Ratings apply to flanged fittings of the designated class, including flanges, flanged valves, and flanged end fittings
For temperatures below −20 °F (−29 °C), consult ASME B16.5 for specific material limitations
