Check the pressure vessel and process operating specification (Process Data)

• Material properties of the fluids used
  - Gas or Vapor : Mol weight, Specific heat ratio, Compressibility coefficient
  - Liquid : Specific gravity, Viscosity
• State of the fluids used : Gas, Vapor, Steam, Liquid, etc.
• Operating condition : Static, Pulsation(Oscillation), Cycle, etc.
• MAWP(Maximum Allowable Working Pressure or Design Pressure) of pressure vessel
• Maximum operating pressure and temperature
• Required Capacity
• Set pressure and set temperature of Rupture Disc for rupture
• Back pressure and Vacuum pressure
• Material (Holder/Disc/Accessory)
• Connection(Flange/Fitting) specification
• Installation type of Rupture Disc : Primary, Secondary, Combination, External Fire
• Calculation of operating ratio : Operating ratio = Maximum operating pressure/Minimum rupture pressure x 100
  ※ Minimum rupture pressure = Set rupture pressure - Negative rupture tolerance
