Note: The rotor shall be balanced as described in all the previous paragraphs, within the acceptance limits indicated in table 1 or table 2, depending on rotor type and the criteria presented in current paragraph. In table 1 or 2 the acceptance criteria depend on pedestal stiffness (locked/unlocked), on the bearing static load and on the rotor speed, according to API612, 7 th ed., paragraphs 9.7.6.1 and 9.7.6.2. The values for locked pedestals must be used only if the vibration amplitude exceeds 20 mm/s (see chapter 4).
