Definition(s)


Corrected Hydrotest Pressure

Hydrostatic test pressure multiplied by the ratio of stress value at upset temperature to the stress value at test temperature.

  • NOTE :1 See 4.2.2 and C.7.
  • NOTE : 2 In this definition, the hydrostatic test pressure is that specified by the pressure design code, whether or not the equipment has actually been hydrostatically tested.
